The use of the current driver IC ULN 2003A posed a problem on whether it would help the cause of scanning process of the LED Matrix. Hence the board was decided to be split up into two, the main PIC Board and the Driver board (constituting the Latch-74373 and ULN 2003A).
The PIC Board consists of PIC 16F877A, crystal oscillators, 7805 regulators, SIL Connectors and an ICSP (In Circuit Serial Progaramming) connector.
