u-blox’s F9R dual-band GNSS module is a fully integrated solution for fast time-to-market

u-blox’s ZED-F9R positioning module features the u-blox F9 receiver platform providing a reliable multi-band GNSS sensor fusion solution for industrial applications in a compact form factor. The wide bandwidth allows receiving of many satellite signals in parallel, resulting in the high availability of RTK solutions and quick convergence time. The module operates under an open sky, in the wooded countryside, in difficult multipath environments, and even in covered areas. Designed for autonomous industrial applications like agricultural machinery or heavy trucks, the ZED-F9R is the ultimate solution for applications where control and position availability are critical.

The ZED-F9R module has an integrated inertial measurement unit (IMU) for RTK positioning in obstructed environments. The sophisticated built-in algorithms fuse the IMU data, GNSS measurements, wheel ticks, correction data, and a vehicle dynamics model to provide optimal positioning accuracy where GNSS alone would fail.

The device is a turnkey self-contained solution, which provides the best possible performance: no latencies or similar system considerations to worry about. This eliminates the technical risk and effort of selecting and integrating RF components and third-party libraries such as precise positioning engines.

The C102-F9R application board with a field-configurable CAN converter allows efficient evaluation of ZED-F9R without porting host libraries.

BQ25171-Q1 – 800-mA linear battery charger for 1- to 2-cell Li-ion, LiFePO4, and 1- to 6-cell NiMH

Posted on by mixos

Texas Instruments bq25171-Q1 Linear Battery Charger is an automotive rated 800mA linear charger for 1-cell and 2-cell Li-Ion, Li-Polymer, and LiFePO4, in addition to 1-cell up to 6-cell NiMH battery applications. The device has a single power output that charges the battery. The system load can be placed in parallel with the battery as long as the average system load does not prevent the battery from charging fully within the safety timer duration. When the system load is placed in parallel with the battery, the charge current is shared between the system and the battery.

The Texas Instruments bq25171-Q1 has three phases for charging a Li-Ion battery: precharge to recover a fully discharged battery, fast-charge constant current to supply the bulk of the charge, and voltage regulation to reach full capacity. The device charges a NiMH in constant current mode only and terminates the charge cycle when the programmable timer expires or the battery voltage exceeds the VOUT_OVP threshold. In all charge phases, an internal control loop monitors the IC junction temperature and reduces the charge current if an internal temperature threshold, TREG, is exceeded.

USB UPDI Programmer PCB for AVR Micrcontrollers

Posted on by DM

AVR is a microcontroller family developed in 1996 by Atmel, now acquired by Microchip Technology since 2016. AVR generally refers to the 8-bit RISC architecture line of ATMEL AVR microcontrollers. They are very popular in embedded systems. They are very common in maker and hobbyist embedded applications and they are also included in Arduino boards. AVR is based on the modified Harvard architecture in which the program and data are stored in separate physical memories. They allow reading data items by special commands. In AVR architecture, Flash memory, EEPROM, and SRAM are all integrated on a single chip. This eliminates the need for external memory.

AVR Programming Methods

In-system programming uses the SPI (Serial Peripheral Interface) which is a full-duplex master-slave-based interfacing technique. The synchronization is done by the rising or falling edge of the clock applied. The disadvantages of the SPI interface are that the speed depends on the target clock and four pins are utilized in the interface. SPI is a very simple type of programming interface. Then comes JTAG which was introduced in 40 pin AVRs. In JTAG, the speed is faster and does not depend on the target clock. But it also needs four port pins for usage.

The TPI Interface was introduced in low-end microcontrollers like some selective microcontrollers in the ATtiny family. It is a 2-wire interface that uses reset as clock and another dedicated data pin. PDI interface is very similar to the TPI interface. It is fast and can cope up with a baud rate of 230,400. UPDI interface is the latest interface by Microchip technologies. It is used in almost all new AVR microcontrollers like tinyAVR, megaAVR, and AVR-Dx. This programming interface is a cross between Debug-Wire and PDI but, it only uses a single line like Debug-wire. However, it is a serial interface without a clock so, the speed is not as fast as PDI.

UPDI Programmer PCB

Stefan Wagner from Germany designed a simple programmer which can program new AVR microcontrollers. The USB-to-serial chip used here is CH330N. It comes in an easy SOIC-8 package and only needs few components to work. In addition, it works fine with both 3.3V and 5V. UPDI interface only needs 3 pins: VCC, GND, and UPDI. First of all, USB to serial conversion is done by the CH330N IC. Then the serial pins RX and TX are tied together with a 4k7 resistor or any suitable resistor and that node is connected to the UPDI pin of the AVR device. The schematic of the board is as follows.

Source: https://github.com/wagiminator/AVR-Programmer/blob/master/PyUPDI_Programmer/PyUPDI_Programmer_schematic.pdf

The programmer works with pyupdi and Arduino IDE. pyupdi is a Python utility for programming AVR devices with the UPDI interface using a standard TTL serial port. This allows makers and designers to program AVR microcontrollers from their favorite environments and languages like Arduino IDE which uses C/C++ or Raspberry Pi environment which uses Python.

Quicklogic QuickFeather Alexa Close-Talk Reference design

Posted on by Emmanuel Odunlade

While voice/speech-controlled embedded devices and systems are more popular thanks to the success of devices like the Amazon Alexa, their design is still quite a hassle due to the complexity of the engineering and algorithms involved. Since Alexa Skills became a thing, and Amazon opened up device APIs and SDKs that allow the integration of Alexa into devices, the hassle on the software side has reduced, but the hardware challenge still existed as there were no plug-and-play, easy-to-use, optimized audio modules in the market.

All of these reasons put together was why fabless semiconductor manufacturer, Quicklogic, developed the EOS S3 ultra-low-power multicore MCU which featured best-in-class audio front-end and powers Quicklogic’s Quickfeather platform, which was developed to make building voice-based embedded solutions easier.

Based on (and compatible with) Adafruit’s open-source Feather Board, the Quickfeather was designed to enable the next generation of low-power Machine Learning (ML) capable IoT devices, and this combined with the QuickLogic’s Open Reconfigurable Computing (QORC) Initiative, and the EOS™ S3 Voice Processor, could be used to create superior user experience and long battery life voice-based system.

To shorten time to market for designers using the platform and make leveraging the potentials in these combinations easier, Quicklogics recently released the QuickFeather Alexa Close-Talk Reference design; created for Voice-Initiated, Hands-Free, Alexa Built-In Devices with Close-Talk Support.

According to Quicklogics,

“This is the first available always-listening, Close-Talk qualified smart hearable reference design based on QuickLogic’s ultra-low-power Arm® Cortex®- M4 Microcontroller”

and it can be used by designers and manufacturers to “evaluate the “Alexa” Built-In Close-Talk experience, optimized for battery-powered products” and build Proofs-of-Concept.

The EOS S3 integrates Sensory’s Low Power Sound Detection (LPSD) technology and runs DSP Concepts’ TalkTo noise suppression and beamforming technology that helps create an intuitive voice-based system, but beyond the reference design also shows how can integrate motion, and other Artificial Intelligence (AI) and Machine Learning (ML) use cases based SensiML’s AI Software Platform that already supports QuickLogic’s QuickFeather development kit.

Some highlight features of the Reference Design include:

  • Alexa Wake Word Engine (WWE) running in the EOS S3 voice processor
  • Hardware-optimized Low Power Sound Detection (LPSD) technology from Sensory™
  • Support for one or two microphone use cases with DSP Concepts’ TalkTo noise suppression and beam forming technology
  • Connectivity to Alexa Voice Service via Wi-Fi
  • Built on top of 100% open-source hardware QuickFeather dev kit and QORC open-source software tools
  • Comes with a QuickLogic QuickFeather Development Kit including the EOS S3 Low Power Voice Processor – Supported by 100% Open Source Hardware Development Kit and Software Tools
  • Espressif ESP32-WROVER-E WiFi Development Kit for WiFi connectivity
  • Adafruit I2S Audio Decoder for supporting playback from Alexa Voice Service directly to a standalone speaker
  • QuickLogic microphone daughtercard that supports variable microphone spacing
  • QuickLogic sturdy PCB cradle to reliably connect all components together

The reference design board is available for sale on the Quicklogics website for $149.

More information on the features of the board and its purchase, along with a manual showing how to use it can be found on the products page on Quicklogic’s Website.

RP2040 M.2 Card with M.2 Connectivity Form Factor

Posted on by Saumitra Jagdale

RP2040 M.2 card

There has been a lot of discussion about the Raspberry Pi’s RP2040 SoC in the past few months after the release of the Raspberry Pi Pico. The RP2040 SoC is also popular for its high-frequency clock covering a large range of applications at a very low cost. Timonsku a hardware designer has come up with a design for the M.2 interfacing of the SoC. This allows the miniaturization of the hardware at low power requirements. The edge connector of the design has a size of M.2 B key.

Timonsku’s design is an RP2040 M.2 card consisting of an RP2040 SoC, a WS2812 intelligent control LED, and a Qwiic connector. WS2812, an intelligent control LED light source in which the control circuit and RGB chip are combined in a package of 5050 components. It is a “simple, scalable and affordable full-color LED”. The board also comes with external GPIO pins allowing the input for the program from outside the CPU or providing the output to the user. The board also has reset and boot buttons on it.

Twitter Thread of RP2040 M.2 Card

Additionally, M.2 form factor is popular in SSDs. It is also called the Next Generation Form Factor (NGFF) due to its internal mounting capacity. This allows compatibility with the computer expansion cards and similar connectors. It is a good alternative to the mSATA standard, which uses the “PCI Express Mini Card physical card layout and connectors”.

There has been a discussion on the interfacing of the board with Desktops or Laptops as they come with M.2 slots. However, according to Timonsku, the M.2 slot of the RP2040 M.2 card may not be used with USB signals. As the M.2 specification does not compulsorily require them. Also, it would be difficult to automate the board while it is present on the laptop or computer. Hence, GPIO-level access would be necessary to work on the boot and reset signals.

Piunora Carrier Board

The Twitter thread of Timonsku shows the compatibility of the RP2040 M.2 card with the Piunora carrier board. This carrier board is also compatible with the popular Raspberry Pi CM 4 and transits it to Arduino R3 like form factor. Piunora carrier board has completed its goal of funding on the Crowd Supply at this point time.

The RP2040 M.2 card is still in the design phase and it is probable that the design would be soon open-source. For more information and updates on the card, you can keep checking Timonsku’s Twitter thread.

Electromagnetic near-field PCB Probes are open source

Posted on by DM

In modern compact electronic circuits, there are several components on a confined PCB area, and so, the electromagnetic effects induced from one component may affect the surrounding components. This disturbance is known as Electromagnetic Interference (EMI). The source of the radiation must be identified in PCBs to predict the EMC of electronic circuits. Electromagnetic compatibility (EMC) is the ability of electrical equipment and systems to function acceptably in their electromagnetic environment, by limiting the unintentional generation, propagation, and reception of electromagnetic energy which may cause unwanted effects such as EMI. Near-field scanning is the general method for identifying radiation sources in PCBs.

Electromagnetic near-field scanning

Near-field scanning is used for estimating localized electromagnetic emissions. The far-field is a region in which the field acts as normal electromagnetic radiation. But in the near-field region, electric and magnetic fields can exist independently. Additionally, in the near-field region, one type of field can dominate the other. E-field and H-field probes are used for electromagnetic near-field scanning. E-field probe measures point-to-point the electric field strengths locally. On the other hand, the H-field probe measures the magnetic field strengths locally.

E-field and H-field probes: An overview

The E-field probe consists of a short dipole antenna, a detector diode, a non-perturbing transmission line, and a readout device. Three orthogonal dipoles are generally used in an E -field probe to provide a response that is nearly isotropic for all polarizations of the incident field. Optical fibers, together with a suitably modulated light source, may be used to form a wide-band non-perturbing data link from the dipole and detector to a remote readout [1].

The H-field probe consists of a printed circuit magnetic loop and a transmission line. The magnetic flux from the loop will induce a high-frequency waveform that travels through a transmission line to the receiver. The transmission line is mostly a microstrip line.

Source: https://charleslabs.fr/en/project-Electromagnetic+interference+mapping

Implementing near field E-field and H-field probes on a printed circuit board is difficult mainly because it involves designing and implementation of non-perturbing transmission lines.

The below shown near-field probes are designed by Ketan Desai. He is a student of Electrical Engineering at the University of British Columbia.
