Description
The sensor is a combination of 3-axis digital gyroscope, accelerometer and compass. It allows you to measure acceleration, magnetic field and angular velocity in the configurable ranges. In addition, built-in barometer allows you to measure the pressure and thanks to it, also the height above sea level. The module communicates via the I2C bus, it is supplied with the voltage 3.3 V to 5.5 V.
Connection
Leads are the soldered, straight goldpin connectors of 2.54 mm pitch. Thanks to them, possible is the connection of the board with the main module (e.g. Raspberry PiorArduino) viawires. The module communicates via the I2C bus.
