Heading Board

The Heading Board is a small board containing the HDPM01 compass module by HopeRF. For some reason, there is also a barometer and a temperature sensor on this module - which you can ignore if all you need is a compass, i.e. a 2-axis magnetometer. Each of the two magnetometer axes has 12-bit accuracy, and a sensitivity of 512 counts per Gauss. There is a “HeadingBoard” class in the Ports library to interface with this sensor and read out all three on-board sensors.


There is nothing to configure.
