First off, I’m not sure how much you need to expand, but you can actually get a fair number of extra LEDs with the hardware that you have. The Peggy 2 has 25 rows and columns on board, but the LED driver chips actually support 32 columns. The extra seven columns are broken out on the PCB as A0 – A6, by U5. So, if you have six rows, using these extra pins will get you 42 extra LEDs. The only downside is that you’ll have to modify the code to include those extra locations.
