A control board is necessary to operate the amplifier SiPM electronics described above. The SiPM bias voltage needs to be adjusted on a sensor by sensor basis due the the wide spread of SiPM breakdown voltages, possible differing temperature conditions and to compensate for variations of optical channel efficiency. Additionally, the amplifier boards may be set into high gain (for single photon counting diagnostic mode) and regular operating regimes. Monitoring of voltage levels and temperature on board the amplifier board is another function that ought to be filled. For these purposes, the [[SiPM digital control board|Digital Control Board]] was designed.
