GND-stitch vias From 77735c00cc3285131373f5cfc61b82eab5963d12 Mon Sep 17 00:00:00 2001 Subject: [PATCH] Add kicad schematic, some diylc noodling Initial stab at a 10-step panel layout Initial stab at a 10-step sequencer (up to 10) https://www.eddybergman.com/2022/04/8-step-sequencer-v2.html very similar core to MK's, but it's unclear whether JLCPCB is still the best option. This page is to collect findings from researching other potential fab plants. Our standard design is 1.6mm thick, 2-sided copper clad fiberglass. ENIG is unnecessary.
