Revision History
Rev 0.0 = Inital Release
Rev 0.1 = Values of R32/R35 swapped
Rev 0.2 = R38 added, R33 not fitted
Rev 0.3 = R39 added, R36 = 0R
Rev 0.4 = R33, R36, R39 new values
Rev 1.0 = new board layout / circuit
Rev 2.0 = new board layout / circuit
Rev 2.1 = Layout modified for better
matching RGB LEDs
