Silicon Labs BG22E, MG22E, FG22E wireless MCUs target energy harvesting, battery-free IoT devices

BG22E MG22E FG22E energy harvesting wireless microcontroller

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 eliminate the need for batteries. The MG22E is similar but embeds an 802.15.4 radio for Zigbee connectivity, and the FG22E provides a 2.4GHz proprietary plus the Cortex-M33 is clocked up to 38.4MHz. Silicon Labs BG22E, MG22E, FG22E specifications: MCU – Arm Cortex-M33 @ 76.8 MHz with DSP and FPU (38.4 MHz for FG22E) Memory – Up to 32 […]

$4.99 ESP32-S3-Tiny board measures just 23.50 x 18 mm

waveshare esp32 s3 tiny kit a mini development board

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 we covered last year. However, what sets this board apart is its 34 I/O pins, compared to the 23 found on the RP2040-Tiny board, and wireless connectivity. We’ve also written about several other boards with compact form factors, such as the Unexpected Maker NANOS3 board (28 x 11 mm), […]

Unexpected Maker NANOS3 might be the world’s tiniest ESP32-S3 module, yet fully-featured

Unexpected Maker NANOS3 A ESP32 S3 Powred Dev Board

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 solar input, the Waveshare ESP32-S3-Relay-6CH, the ESP32-S3 4G dev boards and more feel free to check those out if you are interested in ESP32 boards with advanced features.

ESP32-S3 PowerFeather board supports up to 18V DC for solar panel input

ESP32-S3 PowerFeather

The ESP32-S3 PowerFeather board is an Adafruit Feather-shaped ESP32-S3 WiFi and BLE IoT board that can be powered by a Li-Ion or LiPo battery and supports up to 18V DC input for direct connection to a solar panel. The developer told CNX Software that the main differentiating factor from other ESP32-S3 development boards was “its extensive power management and monitoring features” with a wide DC input range, supply and battery monitoring, and battery protection features. ESP32-S3 PowerFeather specifications: ESP32-S3-WROOM-1-N8R2 MCU – ESP32-S3 dual-core Tensilica LX7 up to 240 MHz with 512KB SRAM, 16 KB RTC SRAM Memory – 2MB QSPI PSRAM Storage – 8MB QSPI flash Wireless – WiFi 4 and Bluetooth 5 LE + Mesh; PCB antenna USB – 1x USB-C 1.1 OTG port for power and programming Expansion 2x 16-pin 2.54 mm pitch headers with 23x multi-function GPIO: UART, I2C, SPI, I2S, SDIO, PWM, CAN, RMT, Camera, LCD […]
