Waveshare developed the RP2040-LCD-1.28, which is an MCU board that combines a good price with a nice performance. The fact that it has a 1.28-inch LCD round display, a Li-ion battery charger, a 6-axis sensor (3-axis accelerometer and 3-axis gyroscope), and so on, in addition to adapting all GPIO and Debug headers, enables you to develop and integrate it into products quickly and easily despite its diminutive size. The Waveshare RP2040 uses the RP2040 microcontroller, as its name suggests.
Raspberry Pi RP2040 has two Arm Cortex M0+ processors (up to 133MHz), 264kB of SRAM, and 2MB of Flash memory on the chip. The built-in display is a GC9A01A, which is a 1.28-inch IPS LCD display that can talk over SPI. The IMU (QMI8658C) has a 3-axis gyroscope and a 3-axis accelerometer that work together. Both of these sensors have a resolution of 16 bits. The 1.27-pitch female headers can be used to get to the GPIOs. But the product page says that some of these pins “are multiplexed to the internal circuit.” There are 2x SPI, 2x I2C, 2x UART, 4x 12-bit ADC, and 16x PWM channels that can be used for communication. The board also seems to have an MX1.25 header for a rechargeable and dischargeable 3.7V lithium battery.
RP2040 MCU chip was designed by Raspberry Pi in the United Kingdom. It contains a Temperature sensor, accurate clock and timer on-board, accelerated floating-point libraries on-chip, and 8 x Programmable I/O (PIO) state machines for providing support for bespoke peripherals.
NOR-Flash memory of 2 megabytes is also included. The screen has a resolution of 240×240 pixels and measures 1.28 inches diagonally. I/O Interfaces has roughly 30 GPIO muxed pins (with female headers), 1x IMU (3-axis gyroscope and 3-axis accelerometer), and 1x Temperature sensor. There is one USB Type-C connection. Additional features include a button labeled 1x Reset as well as a button labeled 1x Boot. The power comes from a single Lithium battery that has a connector for both charging and discharging.
Here is where you can find the Wiki page for this product. On GitHub, you can also find a clock demo project made by Daniel Wienzek. The Waveshare RP2040 board can be bought on ThePihHut.com for £17 (about $18.13).
A Geek Club is a group of designers and engineers who make electronic construction kits for people in over 70 countries around the world who are interested in learning more. Their engineering and robotics kits are made to stretch your mind, improve your skills, and help you learn more about electronics and space. They made a set of 5 very detailed electronic building kits that were inspired by NASA and other space agencies around the world. Choose from the International Space Station, the Apollo Lunar Module with Moon Rover, the James Webb Space Telescope, the Solar Orbiter, or the CubeSat NEA Scout. Each kit comes with PCB parts that are already made, an instruction manual, an educational book about circuitry, and a lot of parts (plus extras, just in case!)
The International Space Station (ISS) was built in 1998 by experts from 15 countries. It is a huge project. It’s a sign of unity and new ideas. The biggest thing ever made by Geek Club. It has solar panels that will actually power it, a flexible PCB, a DIY model stand with a wire for hanging the display, and solar panels that will actually power it. The size is 21.7 by 10.8 by 14.2 inches (550 x 275 x 360 mm). It was made by NASA (United States), Roscosmos (Russia), ESA (Europe), CSA (Canada), and JAXA (Japan).
In 1969, the Apollo 11 Lunar Module Eagle (LM) and Moon Rover (LRV) were built. They are a historic and well-known spacecraft that took us to the moon for the first time. It comes with a Moon Rover that you can put together and drive. Apollo is about 3.9 by 3.9 by 2.9 inches (96x99x75). Moon Rover is about 1.9 by 1.1 by 1.3 inches (48x27x32). NASA came up with it (United States)
The James Webb Space Telescope (2022) is the next generation of space telescopes. It will be almost a hundred times more powerful than The Hubble. It will tell us where the universe came from and take us to the edge of what we know. It has a PCB that is covered in gold. The size is 7.1 by 4.9 by 3.9 inches (180x125x100mm). It was made by NASA (United States), ESA (Europe), and CSA (Canada)
Solar Orbiter, built in 2020, is a super-heat-resistant Sun-observing satellite that will let us look around the sun closer than ever before. It even has solar panels that will power it! It comes with a DIY model stand that has a wire display hanging from it. The size is 18.7 by 14.2 by 6.8 inches (475X360X175mm). It was made by ESA (Europe) and NASA (United States)
After the Artemis I Launch, NASA made a solar sail for the Cubesat Near-Earth Asteroid Scout to explore a small asteroid. The spacecraft NEA Scout will study an asteroid that is about the size of a school bus. This is the smallest asteroid that has ever been studied by a spacecraft. This mission will help us keep other asteroids from hitting our planet. It has a gold-plated PCB, solar panels to power it, and a ceiling wire to hang it from the ceiling. Size is 17.7 by 17.7 by 6.1 inches (450x450x155mm). The NASA’s Marshall Space Flight Center is in Huntsville, Alabama, and NASA’s Jet Propulsion Laboratory is in Pasadena.
The Space Kit has a soldering iron, a soldering iron stand, solder wire, a filing tool, tweezers, pliers, a soldering iron cleaner, protective glasses, a magnifying lens, PCB panels with dozens or even hundreds of parts, a flexible PCB, solar panels, and SMD LEDs. The parts of different models differ.
European computer company Olimex Ltd. has created Agon light a budget-friendly microcomputer and microcontroller on one small board. Bernardo Kastrup designed the AgonLight and the Quark firmware was developed by Dean Belfield. The module is the cheapest and fastest 8-bit microcomputer ever made as per the claims by Olimex Ltd. Agon Light isn’t a microcontroller development board like an Arduino nor a conventional single-board computer like a Raspberry Pi, but rather something in-between the two. It is designed using KiCad instead of EasyEDA.
This project is open-source hardware and software. Agon light can also be seen as an embedded basic computer as it has plenty of GPIOs that allow users to interact with components and modules.
Hardware Specifications of Agon Light
The CPU of the module are ZILOG’s eZ80F92 which runs at 18.432 Mhz clock speed. The unit has 128KB on-chip flash program memory and an extra 256-byte configuration flash memory.
The system memory is 512KB of SRAM. 8MB of PSRAM is dedicated to audio/video memory.
Also, the CPU is packed with 8KB SRAM and has 24-Bit GPIO. 2 universal asynchronous receiver-transmitter(UART) are also available on the CPU.
Agon light uses the Espressif ESP32-PICO-D4module as a VDP (video display processor) which operates at 240MHz. The ESP32-PICO-D4 also handles audio output.
The module contains a PS/2 keyboard port and a MicroSD card slot for storage.
Connectivity Features of the Module
Agon light has a VGA port for video output with 640×480 resolution and 64 simultaneous colors. The power is delivered by a USB-C connector which is a good choice as all new phones, tablets, and other devices use USB-C for charging and data transfer. The board is built for maximum flexibility, which means there are lots of options to do a single task. Instead of having to program kernel code in assembly to write to EPROM, its entire firmware can be programmed in C language. It can be done with freely-available tools such as Arduino IDE and Zilog’s ZDS-II IDE.
Agon light is an 8-bit microcomputer that boots into a basic programming interpreter. This device is for users who are into retrocomputing. It’s like old-school ZX spectrum or Commodore 64 computers but with much more capabilities. Due to modern hardware and interfaces, the possibilities of the module have increased drastically. In the past when cartridges were used to store games the Agon light used microSD which is much faster and more massive in storage capabilities. It is not just a modern version of old 8-but computers. The amazing connectivity features enable the module to interact with various other devices.

The Priority Encoder is a combinational logic circuit that produces an equivalent binary code at its output pins, unique to each combination state of its inputs. As discussed in previous articles, an encoder produces a unique binary code that is related to a specific input combination, and the inputs handled by an encoder are given by 2n. The binary code then can be processed through a Decoder to obtain the original input combination. The Priority Encoder works in a similar way and produces a binary code but with the highest priority.
From the Multiplexer article, it is known to connect one of its input lines to only output depending on the address or select lines. The Priority Encoder can be used to produce the output address of select lines with the highest priority. The Priority Encoder with an “n” number of bits can encode 2n input lines. For example, a 2-bit Priority Encoder can encode 22 = 4 input lines. Similarly, the 3-bit & 4-bit Priority Encoders can encode a total of 8 & 16 input lines, respectively. Therefore, the commercial IC packages include 4 to 2, 8 to 3, and 16 to 4 configurations of lines.
The 4-to-2 Bit Binary Encoder
The binary encoder produces an equivalent binary or Binary Coded Decimal (BCD) code of the input line having a logical state of “1”. The binary encoder expects to have only one of the input lines to have a logical state of “1”. In the following figure, a typical 4-to-2 Encoder along with its truth table has been shown.
The output lines (Q0 & Q1) output a binary code to encode four input lines (D0, D1, D2, & D3). When D0 is “HIGH” then both outputs are “LOW”, similarly, a “HIGH” state of D1 input enables only Q0 to “HIGH”, and other inputs are encoded, accordingly. In an ordinary encoder, there is only one input with a logically “HIGH” state and can produce the wrong output when it has more than one input with a “HIGH” state. For example, when both D1 and D2 are “HIGH” then it would produce an output of “11” which belongs to the input address of D3 which is completely wrong.
The simplest way to overcome such a problem is to prioritize the inputs and when there is more than one input with a “HIGH” state then produce output code corresponding to the input with the highest designated priority only. So, the encoder which prioritizes the binary inputs to produce an equivalent binary code is called a Priority Encoder or P-encoder.
Parity Encoder
The Priority Encoder considers the priority assigned to each input and outputs the binary code at its outputs, accordingly. The output binary code of the input with the highest priority will be produced while all other inputs with lower priority will be ignored. So, by knowing the priority of each input, one can easily designate the address of the currently active input. The Priority Encoder comes in a variety of commercial packages depending on the number of inputs and, most commonly, used is an 8 to 3 Bit Priority Encoder which encodes eight (8) input lines to three (3) bit binary code considering priority.
The 8-to-3 Bit Priority Encoder
In the following figure, an 8-to-3 Priority Encoder has been shown along with its truth table. The 8-to-3 Bit P-encoders are available in commercial IC packages and 74LS148 is a TTL family 8-to-3 Bit Priority Encoder. The Priority Encoder typically sets the priority of its inputs depending on their ascending order. Considering eight (8) inputs from D0 to D7, the D0 input will have the least priority compared to other inputs and, on the other hand, the D7 will enjoy the highest priority. For example, if inputs D2 and D5 are active, simultaneously, then the input D5 will be given priority over D2 because of its higher order.
The truth table below shows a number of input conditions as “don’t care” and are labeled as “X”. This means that the output is not affected by any condition of either “0” or “1” at these “X” values. From the truth table, it is also observed that “don’t care” conditions enable the accounting of priority function at each of these input conditions.
The above truth table gives the following algebraic equations for the outputs of the 8-to-3 Bit Priority Encoder and the equations are simplified further to obtain reduced equations.
The Output Expressions of the 8-to-3 Bit Priority Encoder
The reduced expressions of the parity encoder are further simplified by ignoring the “don’t care” or zero input conditions.
The Logic Diagram of 8-to-3 Bit Priority Encoder
From the above-simplified expressions, following the 8-to-3 Bit Priority Encoder can be constructed as shown below:
Applications of Digital Encoders
Digital encoders have a number of applications in digital circuits where a large number of conditions are encoded in smaller data bit sets. The major applications of digital encoders are described below:
Interrupt Requests
In digital systems, the Priority Encoders are used in connecting different peripherals or services to a microprocessor through interrupt requests. The multiple peripherals or I/O devices such as a keyboard, mouse, printer, scanner, or disk drive are each allocated with a priority level for an interrupt request. The microprocessor on interrupt request checks the interrupting devices and connects with the one having the highest priority and, using this way of communication, the microprocessor knows to which device it is communicating and sets the protocol, accordingly. Using the Interrupt Requests not only alerts the microprocessor or microcontroller that a device wants to communicate but also ensures that the devices are served in order according to their priority levels.
Rotary/ Position Encoder
The Rotary or Position Encoders are frequently used in rotating or mechanical parts to determine the position of a rotating object. The most common applications include robots, rotating knobs, navigation systems, electric gates, etc. The rotational movement is divided into a number of segments or positions which gives the proportion or percentage of total displacement or rotation. Each segment or position drives the input lines of an encoder which produces a binary code of that specific position and is processed in the microprocessor, accordingly. The following figure shows a rotating knob that is divided into eight (8) segments and each segment is given a total percentage of rotation covered. The segments can be indicating to any specific information and can be driven through a sensor such as a compass or motor.
The following table shows the expected output binary code of the above rotary encoder.
Keyboard Encoder
The QWERTY keyboard typically uses 104 keys comprising of alphabets, numbers, special characters, etc., and is not feasible to have a dedicated data channel wired for each specific key. Instead, a Priority encoder is utilized to reduce the number of data wires at the output and the 104 keys of a keyboard are converted into American Standard Code for Information Interchange (ASCII). Each ASCII encoded data comprises of 7-bits which can hold information of 27 = 128 signals or keys. So, whenever a key is pressed on the keyboard, an “ACTIVE” or “HIGH” signal of that key is sent using one of its designated spaces from 0 to 127, and from this computer recognizes which specific key has been pressed on the keyboard.
Conclusion
The Encoder is a combinational logic circuit that produces a specific binary or BCD code at its outputs in response to the active input(s). The Encoder converts 2n inputs to an n-bit specific code and, thus, can help in the reduction of signals for the transfer of information using the Encoder–Decoder combination.
The Binary and Priority Encoders are the most commonly used Encoder types. The Binary Encoder is the simplest form of Encoder and is constructed using OR, or AND gates. However, it is prone to producing the wrong output when more than one active input is encountered.
The Priority Encoder considers the designated priority of each input line when producing output code and, as such, overcomes the constraint encountered during multiple active inputs of a standard Binary Encoder.
The Priority Encoder outputs binary encoded data of the inputs with the highest priority when there are multiple active inputs and ignores the rest of the active inputs.
The Priority Encoders are used widely in digital systems where multiple input and output interfaces are utilized for information transfer. For example, they are used in Interrupt Handlers to process and distinguish between high and low-priority interrupt requests. In Rotary or Positional Encoders, a specific binary code is assigned to determine the rotational or linear movement by designating different portions. Also, Keyboard used an encoder to reduce the number of data wires required for the transfer of data to a computer.
Rohm has introduced a high-efficiency 20-V N-channel MOSFET, targeting small, thin devices including smartphones, wearables, and hearables.
Rohm Semiconductor has developed a compact, high-efficiency 20-V N-channel MOSFET in a DSN1006-3 WLCSP (1.0 × 0.6 mm) package, delivering greater miniaturization for small, thin devices, including smartphones, wearables, and hearables. The RA1C030LD also delivers safer operation thanks to a unique insulated package structure.
Rohm said it leveraged the company’s IC manufacturing expertise to significantly reduce wiring resistance, which has increased with conventional discrete processes, resulting in a compact power MOSFET with low power loss.
In addition, by taking advantage of the company’s proprietary IC process, the RA1C030LD delivers lower power dissipation along with greater miniaturization. Rohm said the figure of merit is 20% lower than standard package products in the same package size (1.0 × 0.6 mm).
The company also offers a unique package structure that provides insulated protection for the side walls, reducing the risk of short-circuit due to contact between components in compact devices that use high-density mounting to save space, said the company. Rohm said it will continue to develop products with lower on-resistance in smaller package sizes that contribute to environmental protection by improving efficiency in compact devices.
The RA1C030LD MOSFET is available via Rohm’s online distributors now: Digi-Key, Mouser, and Farnell. The device also is scheduled for release from additional online distributors.
