Null, "netclass_assignments": null, updates to rev 2 beta by adding +5V, and both trigger/gate and CV on the larger board underneath the smaller board. #Kicad 7 # 2-layer, 1oz copper condition "A.Type == 'track' && B.Type == 'track'" ; DRILL file {KiCad 5.1.10-88a1d61d58~90~ubuntu20.04.1} date Sat Aug 7 10:22:31 2021 e6b834b08c Fix floating pin for op amp in schmidt inverter mode, maybe both 7808 and hex inverter trigger are unnecessary?
