Overview

Wi-Fi 6, BLE and 802.15.4 (Thread, Zigbee, Matter)

The ET-M03 is built around the Espressif ESP32-C6 — RISC-V 160MHz + 20MHz LP core, 512KB SRAM, 4MB flash.

Two Qwiic / STEMMA QT connectors let you chain it with other boards without soldering, and the 2.54 mm header fits a breadboard.

Designed in Dubai by ElectroTrical — the full schematic, BOM and design notes are published below.

Good for

  • Matter and Thread smart-home devices
  • Zigbee sensors for Home Assistant
  • Wi-Fi 6 IoT nodes
