This board provides 3-axis magnetic field data. The resulting vector has to be adjusted by the current attitude before magnetic heading can be produced. This is done in the display computer.
The processor is an Atmel AVR ATMega328 8-bit processor. The CAN controller is a Microchip MCP2515. This communicates with the processor via SPI. The magnetic sensor is a HMC5883L. This communicates with the processor via I2C bus. There is 3.3V and 5V power supplies on the board taken from the 12V power supplied by input.
