SparkFun Triple Axis Accelerometer Breakout - KX132 (Qwiic)
This SparkFun Triple-Axis Accelerometer Breakout is a simple Qwiic breakout for the KX132 digital accelerometer from Kionix. The KX132 is a low-power, 16-bit resolution three-axis accelerometer with four user-selectable acceleration measurement ranges of ±2g/4g/8g/16g and has up to a 10kHz (max) output data rate making it ideal for a wide range of acceleration measurements as well as high-speed applications such as vibration and tap sensing.
The KX132 includes a host of features including Freefall detection, Directional Tap™ and Double-Tap™ detection, tilt orientation detection and more. The Qwiic KX132 can interface with controllers using both I2C and SPI at high speeds so you can use it in an existing Qwiic/I2C chain or on a SPI bus.
