Version 0.1 of the hardware has two significant bugs:

  1. Ground for the ATMega32u4 is not connected to the ground plane. To fix that by soldering the bottom pad of C2 to the ground via next to it.

  2. The pull-up resistor for the HWB button is missing. This can be fixed by soldering a resistor (i.e. 10k) between one of the bottom pins of the button and the +5V pin of the screw terminal.
