A similar amplifier circuit will be designed for every SiPM channel on the board. Those corresponding to a single column will be summed at some stage. Each board, however, will have the capacity for a column of independent channels, since the design of the tagger calls for five such columns in the array.

A compromise will found between fewer boards with more channels (up to 32, given the DAC's limitation) and more boards with fewer channels. The former options may yield cost savings and provide easier maintenance with more space inside the tagger box. On the other hand, a clean design with many channels per board may be difficult both from electronic and light-coupling standpoint.
