Pro Micro, 12 keys, QMK. - matrix is 3x4, diodes all the right way round after the second attempt - qmk compile with my own keyboard folder builds, layout works. Key 7 doubles sometimes, might be a bad joint or could need more debounce - want a rotary encoder, pins are spare, not wired yet - plate is laser cut acrylic, cracked at one screw Have run out of momentum for the moment.
