The Sipeed announced the MetaSense RGBD ToF family of 3D Cameras for microcontrollers and ROS-operated Robots, which is currently in development. The MetaSense 3D cameras use the Time-of-Flight (ToF) principle for providing 3-dimensional information. ToF utilizes light and measures the distance between objects based on the time taken by the light pulses to reflect back by the object.
MetaSense announced the development of two ToF Cameras – A075V, and A010. These cameras provide the coordinates in XYZ-axis, enabling the users to form a point cloud.
The A075V has a higher resolution of 320×240 as compared to the A010 with a resolution of 100×100. Moreover, the A075V has additional an RGB sensor and an Inertial Measurement Unit (IMU). The RGB sensor enables A075V to create colorful point clouds that can be used in applications like 3D scanning and 3D sense reconstruction.
It also features a powerful CPU along with an NPU (Neural Processing Unit) for processing complex data. Users can conveniently access the processed data just through a USB cable. The A010 is cheaper than A075V, making it ideal for beginners. It can be configured to different resolutions like 100×100, 50×50, or 25×25 depending on the microcontrollers used. Both the 3D cameras support integration with ROS1 and ROS2.

Moreover, MetaSense also offers Python SDKs that enable the users to view the 3D depth data on web browsers or ROS. The ToF 3D cameras are still in the prototyping phase and are open for crowdfunding. More information can be found in the Sipeeddocumentation.
M5Stack embedded developers have developed the Thermal2 Unit thermal imaging camera. This is a newer version of the earlier Thermal Unit developed by the same company. The Melexis MLX90640 FIR thermal sensor used in the module is the core component. It has a wide range of temperature measurement abilities starting from as low as -40 deg C, and it can reach up to 300 deg C. It can also withstand an operating temperature in the range of -10 deg C to 60 deg C.
The sensor has a resolution of 32 x 24 px which offers 768 individual measurement points. The device has a 110×75 deg field view and a refresh rate from 0.5Hz up to 64Hz. The refresh rate is programmable as well. The power consumption is only 2.5W, operating at 5V with a current consumption of 500mA.
The MCU used in the device is the ESP32-PICO-D4, with many features included, such as a flash memory of 4 MB, Bluetooth 4.2 radio, and SRAM of 520kB. It is also integrated with two low-power Xtensa LX6 32-bit microcontroller cores, two banks of 8kB in RTC, and 2.4GHz 802.11b/g/n Wi-Fi.
It is a very lightweight module weighing merely 4.9g with a small size of 48mm x 24mm x 8mm. To make the module ready to use, a user-addressable RGB LED and a button is attached. The device can operate in standalone or I2C mode, and a default firmware is already flashed in the module. However, UIFlow or Arduino IDE can be used to program the device, as confirmed by the makers.
Some prominent applications where it can be used are motion detection and visual infrared thermometer. It can also be used for non-contact temperature measurements with high precision. The applications are of course extended to any DIY projects as well. The Thermal2 is now available at a price of $69.90 for purchase at the M5STack Store. A separate cable is not necessary, as an HY2.0-4P cable comes bundled with it.
The Demultiplexer or DEMUX is a combinational logic circuit that connects one input line to one of the several output lines, one at a time. Like a Multiplexer, the Demultiplexer contains no memory, storage, or feedback. Being a combinational logic circuit, its output is solely dependent on the information present on its input lines. Demultiplexing refers to the reverse of the Multiplexing process. As discussed in the previous article, the Multiplexer combines several input lines into a single channel or output line for sending information or data which may be either analog or digital. The reverse of Multiplexing is to combine several output lines into a single channel connecting to an input line. For a multiplexer, there is more than one (1) input and only ONE output. Whereas, for a Demultiplexer, there is only ONE input and several output lines.
The input line is routed or switched to output lines one at a time by the application of a control line(s). Similar to the multiplexers, the demultiplexers are like mechanical rotary switches which select one of the output lines or channels to be switched to the common input.
The Demultiplexers are also classified into Analogue and Digital categories. The Multiplexers and Demultiplexers are used in pairs and should match their construction, signal-handling capabilities, etc.
The selection of output lines in demultiplexers is controlled using separate input lines which are referred to as “Select Lines”. The logical combination of these Select Lines helps in selecting one of the output lines. For example, a logical “LOW” at the select line means to select Output Line-0, and a logical “HIGH” to select Output Line-1. The data output lines are normally in even numbers and are given by 2n. Whereas, the “n” corresponds to the number of control inputs required for the selection of data output lines.
Demultiplexer Symbol
In the following figure, a Demultiplexer symbol has been shown. It is the simplest one-to-two (1-to-2) Demultiplexer.
Figure 1: The Demultiplexer
1-to-2 Demultiplexer
In the following figure, a 1-to-2 Demultiplexer has been shown along with its truth table.
Figure 2: The 1-to-2 Demultiplexer
The above 1-to-2 Demultiplexer is constructed using basic logic gates. The data input line is D and the output lines are Y0, & Y1. The Select or Control Line is indicated by input A. From the logic diagram and given Truth Table, it is obvious that when Select Input “A” is “LOW” or “0” then Output Line “Y0” gets selected as an output. The signals present on input pass through the logic circuit and appear at output “Y0”. Whilst, the Output Line “Y1” gets blocked when Select Line “A” is set to “LOW”. The output selection phenomena get reversed when Select Line “A” is set to “HIGH” or “1” i.e. the Output Line “Y1” connects with the input “D” and Data Output “Y0” gets blocked.
By simply setting the Select Line “A” to “LOW” or “HIGH” logic, the input line can be switched to the outputs depending on the logic level of “A”. The given circuit is acting as a Single-Pole-Double-Through (SPDT) switch. As discussed above, with only one (1) Select line i.e. n=1, the input line can be switched to a total of two (2n = 21 = 2) output lines. The described circuit is the simplest form of a Demultiplexer which is a 1-to-2 Demultiplexer.
The 1-to-2 Demultiplexer is the simplest or basic form of a Demultiplexer which has only one (1) input and two (2) outputs. In order to increase the number of outputs of a Demultiplexer, a 1-to-2 Demultiplexer can be used as a basic building block for the construction of higher-output Demultiplexers. As mentioned above, the number of outputs of a Demultiplexer will be in even numbers so the next stage after two (2) output-Demultiplexer is a four (4) output-Demultiplexer. For a four (4) output Demultiplexer, a total of two (n = 2) Select Lines are required.
1-to-4 Demultiplexer
In the following figure, a 1-to-4 Demultiplexer has been shown along with its Truth Table.
Figure 3: The 1-to-4 Demultiplexer along with Truth Table and Switch Analogy
In the above 1-to-4 Demultiplexer, the Output Lines are Y0, Y1, Y2, and Y3 and the Select Lines are “a”, and “b”. The Boolean expression of the above-given 1-to-4 Demultiplexer is:
The 1-to-4 Demultiplexer circuit acts as a Single-Pole-Quad-Through (SPQT) switch. At any instant, only one of the four outputs will be connected to the input “D” whilst others remain blocked depending on the logic conditions of Select Lines “a” and “b”. For example, in order to connect the Data Input “D” to the Output Line “Y2”, the logic states required are “A=0” and “B=1”. Likewise, other Data Output selections can be made by setting the logic states of Select Lines, accordingly. The selection of Output Lines against the logic states of Select Lines is shown in the following figure.
Figure 4: The logic states of Select Lines and Switching Positions
The output lines of a Demultiplexer can be further increased to 8, 16, … etc. by increasing the select lines to 3, 4, … etc., respectively.
Adjustable Amplifier Gain Application
In the Multiplexer article, an adjustable gain amplifier was constructed using a multiplexer in the feedback. The same can be achieved by using a Demultiplexer but instead of using it in the feedback, it is placed at the input of the amplifier circuit. In the following figure, an adjustable inverting operational amplifier has been shown with multiple input paths depending on the amplification required.
Figure 5: The multiple channel gain amplifier using Demultiplexer
The placement of the Demultiplexer at the input is obvious as it essentially converts a single input to multiple paths. Each path has been set to present a different input resistance which ultimately sets the gain of the amplifier. The gain of the amplifier is mainly dependent on input and feedback resistances. However, in the above configuration, the gain is adjustable using only input resistance as the feedback resistance is fixed. The gain of the input signal (audio) will be set as per Select Lines which are setting the input resistance of the op-amp.
The Demultiplexers are used in the reception of single-input data to distribute over multiple channels, buses, or transmission lines such as in Digital Systems, LAN or Ethernet Switches, etc.
The Demultiplexers are commonly available in commercial I.C. packages such as in TTL: 74LS15138 (Single 1-to-8), and 74LS139 (Dual 1-to-4) or in CMOS: CD4514 (Single 1-16) Demultiplexers, etc. The number of inputs of a Demultiplexer can be increased by cascading the aforementioned TTL or CMOS devices. Most of the commercial I.C. packages come with Enable pin which enables or disables the operation of Demultiplexing.
Conclusion
A Demultiplexer is a combinational logic circuit with the ability to switch a single input line to one of several output lines.
Being a combinational logic circuit, the Demultiplexer’s output is dependent on the state of inputs only and, as such, uses no memory, storage, or a feedback path.
The selection of individual output lines is made through the “Select” or “Control” line(s). The number of “Select” or “Control” lines yields the number of Output Lines that can be controlled i.e. 2n. Where “n” represents the number of “Select” or “Control” lines. For example, in a Demultiplexer with two (n=2) Select Lines, a total of four (2n = 22 = 4) Output Lines can be switched to the common Data Input Line. Because of this, the number of Output Lines is in even numbers.
The digital Demultiplexers are used for the reception of serial data over a single line to distribute over multiple channels, buses, etc. The analog demultiplexers are commonly used in the pre-amplification of audio, and video signals.
The Demultiplexers are commercially available in form of I.C. packages such as 74LS15138 (Single 1-to-8), 74LS139 (Dual 1-to-4), and CD4514, etc.
Arduino has now declared the Arduino IDE 2.0 ready for primetime use, effectively ending the era of the previous Arduino IDE. The Arduino team stated that moving it from the beta version to the general release was a result of the feedback they received from the Arduino community which has helped them focus on what is more meaningful to the wildest user base.
“The enormous amount of user feedback allowed us to identify the weakest spots such as code assist and completion, serial output, loading, and compilation time. We made it all better now,” the team said. “A special mention goes out to Paul Stoffregen who has provided enormous feedback to the IDE development team and has been actively developing the initial support for advanced third-party platforms such as Teensy for IDE 2.0 (currently experimental).”
The latest release version is indeed a big step up from the previous release. It is faster, more powerful, and boasts plenty of new features to help you to develop your code more easily. A big shift towards better usability I must say.
The new version provides a more modern editor, an improved user interface, autocomplete during coding, navigation shortcuts, integrated support for storing sketches in the Arduino Cloud, the ability to quickly switch to and from a dark mode theme, and the ability to run the revamped serial plotter alongside the serial monitor. There’s also a new sidebar to make the most commonly used tools more accessible and a debugger with powerful features like Breakpoints, Step-into, and Step-Over, which help you really understand what your code is doing.
The Arduino team assured users that the new IDE comes with a lot of likable features, though it might take a while to discover and use all the new features effectively.
“Some of them are carry-overs from the “Arduino Pro IDE” that we covered a few years ago, but it’s great to see the software evolve and improve over time. Installation is straightforward, and will automatically pull in any libraries and sketches that you created in previous versions of the Arduino software to ease the transition.”
The latest release can also check for, download, and install updates to the IDE itself without having to manually open a web browser and download the latest installer.
Further details on the stable Arduino IDE 2.0
Download options for Windows, Linux, and macOS, alongside other details, can be found on the software page of the company’s official website while the IDE’s source codes and a support link in case you need any assistance are also available on GitHub.

Colorado-based embedded electronics specialist, SparkFun, has released a compact Qwiic 6DoF IMU breakout board powered by STMicroelectronics ISM330DHCX. The ISM330DHCX is a system-in-package with a high-performance 3D digital accelerometer and gyroscope tailored for industry applications.
The ISM330DHCX’s fundamental parameters are remarkable, delivering wide bandwidth, ultra-low noise, and a selectable full-scale acceleration range of ±2 to up to ±16g. Furthermore, the 3D gyroscope has an angular rate range of ±125 and goes up to ±4000 dps, and it provides excellent stability over time and temperature in addition to having extremely low noise. The implementation of smart and complex sensor nodes that provide great performance at incredibly low power is made possible by an unparalleled collection of embedded features such as a machine learning core, programmable FSM, FIFO, sensor hub, event decoding, and interrupts.
The ISM330DHCX chip features four operating modes:
Mode 1: This is the “peripheral only” mode by default, and it allows you to use either I2C or SPI.
Mode 2: This mode provides an additional I2C port controlled by the 6DoF; up to four external sensors can be added to the device’s I2C controller interface.
Modes 3 and 4: An additional SPI serial port is offered for connecting external devices (i.e. camera module) in addition to the basic I2C peripheral interface. However, Mode 3 is only accessible for the gyroscope, but Mode 4 is available for both the gyroscope and the accelerometer.
No soldering is required to connect the Qwiic 6DoF IMU to the rest of your boards because it connects by default through I2C using our convenient Qwiic Connect System. However, for customers who prefer a soldered connection, the manufacturer routed the I2C signals out to a set of 0.1″-spaced pins.
