Description

  • SparkFun Triple Axis Accelerometer Breakout KX134 (Qwiic)
  • Offers a simple Qwiic breakout
  • Features low-power, 16-bit resolution
  • Capable of measuring ±8 g / 16 g / 32 g / 64 g
  • Ideal for high-g measurements
  • Interface with controllers using both I2C and SPI

The SparkFun Triple Axis Accelerometer Breakout KX134 (Qwiic) is a simple Qwiic breakout for the KX134 digital accelerometer from Kionix.

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.

The KX134 is a low-power, 16-bit resolution three-axis accelerometer capable of measuring ±8 g / 16 g / 32 g / 64 g (user-selectable) and has up to 10 kHz output data rate making it ideal for high-g measurements as well as high-speed applications such as vibration sensing.
