Assembly Notes: From 5040873587dbb57684343269abab88d35cf7124b Mon Sep 17 00:00:00 2001 Subject: [PATCH] Finished PCB, passes all passable DRCs Show-stopping bugs needing bodges: Errant connection between R25 and R1, probably a result of KiCad adding junctions during a component move. This needs to be +1mm between legs -- Don't put R8 so close to R26 - D36/R47 too close Testing before powering up: Clock In - diode to U2-3 - Clock In - diode to U2-3 - Clock Rate - variable resist +6k between U2-8 and U2-9 Reset Sw .
