Description
Description
Example for LED MATRIX DRIVER I am using.
Every Board is deisgned to drive 7 Rows or Columns.
To create COLUMN DRIVER add corresponding LED RESISTORS to DIP16
To create ROW DRIVER add ULN2003A Transistor Array IC to DIP16
Easy hook up multiple Boards by connecting the SIP5 Sockets to next Modul, take care of Flowdriection indicated by arrow
