Silicon Labs xG22E is a family of wireless SoCs consisting of the BG22E, MG22E, and FG22E and designed to operate within an ultra-low power envelope required for battery-free, energy harvesting applications such as electronic shelf labels, Smart Home sensors, remote controls, and so on.
Like the just-announced Silicon Labs MG26, BG26, and PG26, the new xG22E family features a Cortex-M33 core clocked up to 76.8MHz. As an evolution of the low-power BG22, the BG22E offers Bluetooth 5.4 LE connectivity with “Energy Conservation” to further enhance battery longevity and even support designs that ..read more

Waveshare has recently released the ESP32-S3-Tiny mini development board powered by ESP32-S3 wireless MCU and measuring just 23.50 x 18 mm. Due to its compact form factor, it does not include a USB-to-UART converter or a USB port. That is why, you will need an additional adapter board with an FPC cable to program it, which costs only $1. Despite its small size, the board is feature-rich. It includes 34 multi-function GPIO pins, along with Wi-Fi, BLE, SPI, I2C, UART, ADC, PWM, and more.
The design of the board is very similar to the Raspberry Pi RP2040-powered Waveshare RP2040-Tiny board that ..read more

The Open Home Foundation is a non-profit organization that will manage over 240 Smart Home projects, standards, drivers, and libraries including Home Assistant, ESPHome, Zigpy, Piper, and Improv Wi-Fi with the goal of “fight[ing] for the fundamental principles of privacy, choice, and sustainability for smart homes”.
The non-profit was introduced during the “State of the Open Home 2024” (see video embedded at the end of this article) with Nabu Casa – the for-profit company behind Home Assistant – transferring all their projects to the new entity, and the Open Home Foundation will also he ..read more

Louder Raspberry Pi is an open-source home media center based on a combination of the Raspberry Pi Zero W or Zero 2 W and the Texas Instruments TAS5805M DAC. It is an audio entertainment platform created by Andriy Malyshenko of Sonocotta, a Polish electronics hobbyist and maker.
Louder Raspberry Pi incorporates the computing power of the Raspberry Pi Zero and the Hi-Fi audio processing capabilities of TI’s TAS5805M DAC in a compact, aluminum case. The device delivers up to 25W per channel stereo output and is powered via a 65W+ USB-C PD3.0 adapter. It is “aimed to be paired with medium-to-l ..read more

ntttcp (Windows NT Test TCP) is a network benchmarking utility similar to iperf3 that works in both Windows and Linux written and recommended by Microsoft over iperf3, so we’ll test the alternative in this mini review.
iperf3 is a utility of choice for our reviews of single board computers and mini PCs running either Windows or Linux, but we’ve noticed that while Ethernet (up to 2.5GbE) usually performs just as well in Windows and Linux, WiFi is generally much faster in Ubuntu 22.04 than in Windows 11. So when XDA developers noticed a post by Microsoft saying iperf3 should not be used on Wind ..read more

At Embedded World 2024, Microchip announced their new AVR DU family of 8-bit MCUs featuring a full-speed USB 2.0 data interface along with USB-C 15W Power Delivery enabling up to 12Mbps data transfer and charging. They also have features like secure bootloaders and Program and Debug Interface Disable (PDID), which protect your embedded designs.
Based on the Harvard architecture, these MCUs can have up to 64 KB of Flash memory, 8 KB of SRAM, and 256 bytes of EEPROM. Their wide operating voltage range of 1.8V to 5.5V makes them suitable for small, space-sensitive devices, power bricks, and rec ..read more

European engineer, Matej Planinšek of PLab, has developed the FOCn — a medium-power BLDC driver module based on ESP32-S3 WiSoC capable of delivering up to 10A of continuous current. It is compatible with the SimpleFOC Arduino library making it easier to control BLDC (brushless direct current) and stepper motors with the field-oriented control algorithm.
The developer was inspired to create the FOCn module when their search for a custom-made, SimpleFOC-compatible driver module that met all their requirements failed. The name is related to field-oriented control (FOC) and also means “face sla ..read more

Tomeu Vizoso has been working on an open-source driver for NPU (Neural Processing Unit) found in Rockchip RK3588 SoC in the last couple of months, and the project has nicely progressed with object detection working fine at 30 fps using the SSDLite MobileDet model and all three cores from the AI accelerator.
Many recent processors include AI accelerators that work with closed-source drivers, but we had already seen reverse-engineering works on the Allwinner V831’s NPU a few years ago, and earlier this year, we noted that Tomeu Vizoso released the Etvaniv open-source driver that works on Amlogi ..read more

Seon Rozenblum, better known as Unexpected Maker, has launched NANOS3 a development board that claims to be the world’s smallest, fully-featured ESP32-S3 module! This new module packs all the peripherals, and wireless connectivity features of an ESP32-S3 while being even smaller than the TinyPICO Nano. The module features two variants one with an onboard 3D antenna and the other with an u.FL connector.
Previously we have written about TinyS3, FeatherS3, and ProS3 boards from Unexpected Maker we have also covered many unique ESP32-S3 boards like the ESP32-S3 PowerFeather Board with sola ..read more
