• Description
• 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 r-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(TM)and Double-Tap(TM)detection, tilt orientation detection and more. The Qwiic KX132 can interface with controllers using both I2C and SPI at high speeds so you can 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 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.
