ZB-GW03 ESP32-based Ethernet Zigbee gateway works with Tasmota firmware

ZB-GW03 ESP32 Ethernet Zigbee Gateway

ZB-GW03 is an Ethernet Zigbee Gateway compatible with eWelink mobile app and with a design similar to SONOFF ZBBridge gateway but replacing ESP8266 SoC by ESP32 SoC, and adding an Ethernet port. The ZB-GW03 gateway is apparently based on the same Silicon Labs EFR32MG21 Zigbee Arm Cortex-M33 chip and has been hacked to run Tasmota open-source software for people preferring more flexibility and/or integration with OpenHAB or Home Assistant open-source home automation frameworks via Zigbee2MQTT. ZB-GW03 gateway specifications: Main MCU – Espressif Systems ESP32 dual-core Tensilica TX6 processor @ 240 MHz with WiFi 4 and Bluetooth connectivity Zigbee MCU – Silicon Labs EFR32MG21 Arm Cortex-M33 MCU @ 80 MHz with Zigbee 3.0 connectivity Connectivity 10/100M Ethernet, WiFi, and Bluetooth via ESP32 Zigbee 3.0 via Silabs MG21 MCU with support for 128 nodes, up to 200+ meter range One 2.4 GHz Zigbee antenna One 2.4 GHz PCB antenna for WiFi Misc […]

LOLIN S2 Pico – A compact ESP32-S2 board with an OLED display

LOLIN S2 Pico

If you’re into small MCU boards with an integrated display, you’re in luck as LOLIN launched the S2 Pico board with ESP32-S2 and an OLED display about at the time same as LILYGO T-Display RP2040 board we covered yesterday. Wemos/LOLIN S2 Pico board offers WiFi connectivity, a 128×32 OLED display, USB Type-C port for power and programming, as well as the usual GPIO headers in a compact 50×23 mm form factor.

LILYGO T-32C3 – A small ESP32-C3 WiFi & BLE IoT module with 4MB flash

LILYGO-TTGO-T-32C3

We’re slowly starting to see more hardware-based on ESP32-C3 RISC-V processor, and LILYGO T-32C3 is a compact module based on the WiFi & Bluetooth LE processor that includes 4MB flash and a PCB antenna. I’d expect T-32C3 to be eventually found in the company’s smartwatches and development boards, and it joins other ESP32-C3 modules from AI Thinker. LILYGO T-32C3 module specifications: SoC – Espressif ESP32-C3 RISC-V processor @ 160 MHz with 400 KB SRAM, 384 KB ROM, 8KB RTC SRAM, 2.4 GHz WiFi 4, Bluetooth 5.0 LE & Mesh Storage – 4MB flash On-board PCB antenna I/Os – 22x castellated holes with GPIO, 3x ADC, SPI, UART, I2C, Boot, Reset, 5V, 3.3V, GND Dimensions – 23 x 11 x 3.5 mm (4-layer PCB) Note the USB interface is not listed in the specs, but USB DN and DP signals are located on GPIO18 and GPIO19 so USB should also be […]

An ESP32-based BBC Micro:bit clone – Meet Mbits

BBC Micro:bit clone ESP32 Mbits

A few years ago, we noted a BBC Micro:bit clone based on ESP32 WiSoC with Banana Pi ‘s BPI:bit board with an array of 25 RGB LEDs and WiFi & Bluetooth LE connectivity. There’s now another such clone with Elecrow Mbits designed in a way that resembles the BBC Micro:bit v2 board, but replacing the Nordic Semi nRF52833 2.4GHz/BLE SoC with the ESP32 dual-core wireless chip with support for both WiFi and BLE. The specifications between Elecrow Mbits and BBC Micro:bit v2 are close enough, although ESP32 is a more powerful processor, and the MBits board comes with more memory and storage. Power consumption of the BBC Micro:bit v2 should be much better, so if anything needs to run on battery for an extended period of time, it may be a better choice, or you’re gonna need a bigger battery.  The GPIO pinout looks different too, so not all Micro:bit […]
