878 Backpack Connections

Post by nyunker »

I see from your schematics that the anodes for the B and colon display segments are all tied together to ROW1/A1 on the HT16K33 driver IC? Why are the B and colon anodes shared? Rows 8-15 on the driver IC are all free and unused.

I think they wanted to make the PCB as compact as possible.....
