My first project this semester is going to be programming the control boards that regulate the bias voltages for the SiPMs as per the procedures outlined by Alex [https://docs.google.com/document/d/1bxv-7gNciLGODSrxeMywemjbKlv3wrxJTU4ivEoAzwQ/edit?pli=1 here].

After some initial issues with the boards, Dr. Jones and Alex discovered that there was a problem with the Vref of the control boards. With the addition of an extra resistor the problem has been fixed and the first and eleventh boards have been programmed. I started on the second board but there was an issue with the first pin that led us to believe that there is a solder bridge underneath the DAC that is sapping voltage from the pin. This is not an issue that we can fix and therefore the board is bad.
