Out of stockOverview
Cortex-M0+ 64 MHz with SWD and level-shifted Qwiic
The ET-M06 is built around the ST STM32G030F6P6 — Cortex-M0+ 64MHz, 32KB flash, 8KB SRAM, 12-bit ADC, 2×USART, SPI, I2C. It runs from VIN 3.3–5.5V → AP2112K 3.3V; I2C level-shifted to VIN on Qwiic.
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.
