Compass Board time full design details and workingThe Compass Board is a small board containing the HMC5883 3 axis compass module by Honewell. The chip can be configured to 8 different sensitivities, from 0. 9 to 8 Gauss full scale, with read outs up to 160 times per second. There is a CompassBoard class in the JeeLib library to interface with this sensor and read out all three on board compass axes. This board uses an I2C bus running at 3. 3V as interconnect. There is room for a Port compatible 6
