GY-346 High-Performance Accelerometer Module — I2C and SPI Interface

The GY-346 mounts a precision 3-axis accelerometer with configurable range from +/-2g to +/-16g and supports both I2C and SPI communication. The 16-bit ADC per axis provides 1mg resolution at +/-2g range, suitable for detecting small tilt angles and vibration. An interrupt output triggers on configurable threshold events — freefall, activity, tap detection — reducing the need for continuous MCU polling in battery applications.

  • 3-axis accelerometer — +/-2g, +/-4g, +/-8g, +/-16g selectable
  • 16-bit resolution per axis — 1mg at +/-2g range
  • I2C and SPI interface
  • Interrupt output — activity, inactivity, freefall, tap detection
  • 3.3V supply — direct ESP32 and 3.3V MCU connection

Best for

Tilt sensing, vibration monitoring, freefall detection, drone stabilisation, wearable motion tracking, vehicle shock logging, and robotics orientation sensing.

Customer Reviews (4.6 / 5 · 5 reviews)

Christopher R. ★★★★★

Set the range to ±4g for a robotics project and the readings stayed consistent across a full afternoon of testing. I2C hookup took me about five minutes on a breadboard. Only wish the header pins came pre-soldered, but that's minor.

Christopher Y. ★★★★★

Switched to I2C and the GY-346 just worked on the first try; the +/-16g range setting gives me solid readings for my vibration project. Data comes through clean and fast.

Grace T. ★★★★★

Was worried about wiring it up for SPI but the pinout is clean and it took me five minutes. The +/-16g range is perfect for my vibration logging project, and the readings stay stable throughout the day.
