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.


Description

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.


The SparkFun Qwiic Connect System is an ecosystem of I2C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can’t hook it up wrong.
