Accelerometer + gyro with machine-learning core
The ET-S26 is built around the ST LSM6DSOX — ±2–16g accel, ±125–2000dps gyro, FSM + Machine-Learning Core, 9kB FIFO. It connects over I²C 0x6A / 0x6B (JP3) (INT1/INT2) and is powered from VIN 3.3–5.5V, onboard LDO.
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
- Activity and gesture recognition
- Wearables
- Tilt and vibration sensing
