Description

Product description: KX134 - 3-axis I2C Qwiic accelerometer - SparkFun SEN-17589

KX134 3-axis digital accelerometer embedded on a module from SparkFun. The board features low power consumption and 16-bit resolution with selectable acceleration measurement range: ± 8 g / 16 g / 32 g / 64 g, maximum data rate is 10 kHz. Module communicates via I2C or SPI interface. It is equipped with two Qwiic connectors enabling simple connection via I2C interface. It is powered from 1.7 V to 3.6 V.

KX132 accelerometer module also available.
