SparkFun Triple Axis Accelerometer Breakout – KX134 (Qwiic) Hot on Sale

This SparkFun Triple-Axis Accelerometer Breakout is a simple Qwiic breakout for the KX134 digital accelerometer from Kionix. The KX134 is a low-power, 16-bit resolution three-axis accelerometer capable of measuring ±8g/16g/32g/64g (user-selectable) and has up to a 10kHz output data rate making it ideal for high-g measurements as well as high-speed applications such as vibration sensing.

The KX134 includes a host of features including Freefall detection, Directional Tap^™ and Double-Tap^™ detection, tilt orientation detection and more. The Qwiic KX134 can interface with controllers using both I²C and SPI at high speeds so you can use it in an existing Qwiic chain or on an SPI bus.
