Express post delivery (2-5 business days)

A versatile triple-axis digital accelerometer breakout featuring the Analog Devices ADXL343. With selectable sensitivity of ±2g, ±4g, ±8g, or ±16g and up to 13-bit resolution, this sensor handles everything from precise tilt measurement to high-speed motion tracking over I2C or SPI.

Built-in motion detection features make tap, double-tap, activity, inactivity, and free-fall detection trivial — with two configurable interrupt pins. The ADXL343 is a near drop-in replacement for the popular ADXL345, with code compatibility and improved pricing. Onboard 3.3V regulator and level shifting work with any 3V or 5V microcontroller.
