Product description: LSM303DLHC - 3-axis accelerometer and I2C magnetometer - Waveshare module
The sensor is a combination of a 3-axis digital accelerometer and a compass. It allows to measure acceleration and magnetic field in configurable ranges. It communicates through the I2C bus and is powered by 3.3 V.
|
Product compatible with STM32 The manufacturer has prepared a user guide with a sample program for STM32. |
The module supports cascade connection on the I2C bus.
Communication
The I2C interface is used for communication with the central unit. The module has the necessary passive elements for proper operation of the system. The outputs are 2.54 mm goldpin connectors - raster 2.54 mm, which allow the sensor to be connected by wires or directly connected to the contact plate.
