LED Driver
Since you are already using the tlc5927, use two of them in series :) with a forward voltage of 3.7V there will be 0.9V over the led driver. With 15 channels enabled, the power...

There's no way to define fuses using a gui, so you will have to resort to setting fuses using source code. Example: #include FUSES = { .low = LFUSE_DEFAULT, .high = (...
