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) & 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 & Double-Tap detection, tilt orientation detection & more. The Qwiic KX134 can interface w/ controllers using both I2C & SPI at high speeds so you can use it in an existing Qwiic chain or on a SPI bus.
The SparkFun Qwiic Connect System is an ecosystem of I2C sensors, actuators, shields & cables that make prototyping faster & 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, & polarized connections mean you can't hook it up wrong.
