The PCB is designed as a single-sided controller board. k3ng keyer schematic repack

Its modular code design means you can easily select which features to include, which is why the "repacks" exist. The K3NG code can be flashed onto a standalone AVR chip or a full Arduino board, giving hardware designers incredible flexibility. The official K3NG repository ( github
