This PCB takes 16-bits of cathode inputs (abcdefghkmnprstu) and 2-bits of anode inputs (A1, A2) to display values on one of two 16-segment displays. The 16-segment displays are multiplexed: they share common anode pins and are individually selected through their cathode pins to display data. Current-limiting resistors are included on the board. Note that the decimal points are not connected.
