LED and 7 Segment Display Controller for displays with Common Anode.

Deprecated Design, replaced by DOA_7seg Rev.1

Nearly the same as the DOA_7seg_2803. The differences are:

  • for common anode displays
  • different commons driver chip
  • tiny differences in board layout (traces) to accomodate the different commons driver chip
