KX132 accelerometer and Raspberry Pi Pico Arduino example

by rp2040guy71

In this article we connect the ever popular KX132 accelerometer to a raspberry Pi Pico and we will then display readings via the serial monitor window. We are using the Arduino IDE.

Lets look at the sensor first


The KX132-1211 is silicon micromachined accelerometer in the 2 x 2 x 0.9 mm LGA package featuring up to 25.6 kHz ODR and wide bandwidth (4200Hz (XY), 2900Hz (Z)). I²C or SPI digital protocol is supported.

  • Advanced Data Path with user configurable 3 stages consisting of a low-pass filter, low-pass / high-pass filter, and RMS engine.
  • High Temperature Range -40°C to +105°C
  • Integrated Free fall, Directional-Tap/Double-Tap™, and Device-orientation Algorithms
  • Advanced Wake-Up and Back-to-Sleep detection with high-resolution threshold configurable down to 3.9mg
  • Embedded 512-byte FIFO buffer with capability to record data even when being read
  • User-selectable Output Data Rate up to 25600Hz
  • User accessible manufacturer and part ID registers


The SparkFun Triple Axis Accelerometer Breakout is a simple Qwiic breakout for the KX132 digital accelerometer from Kionix. KX132 is a low power, 16 bit resolution three axis accelerometer w/ four user selectable acceleration measurement ranges of 2g/4g/8g/16g & 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 & tap sensing.

512 byte FIFO buffer that continues recording data while being read; Selectable Low Power or High Performance operating modes; Low Power with Integrated Voltage Regulator: High Performance Operating Current Consumption (400Hz ODR + Wake Up Detection): 148 A, Low Power Operating Current Consumption (0.781Hz ODR + Wake Up Detection): 0.53 A, Standby Current Consumption: 0.5 A

Self Test Functionality; Digital I2C up to 3.4MHz and Digital SPI up to 10MHz; 2x Qwiic Connectors; SPI available on PTH Header Pins; I2C Address: 0x1E (0x1F alternate)

Code Example

I used the Sparkfun KX13X library and  this is the default example which worked, there are several examples to experiment with


  This example shows the basic settings and functions for retrieving accelerometer
  data. Other possible Range settings, depending on your accelerometer KX132 or KX134, are
  the following:
