A/caixa_sr2.png and b/caixa_sr2.png differ From f1ff8406b412e95346ec2837fcbe5f8c2630c4ee Mon Sep 17 00:00:00 2001 Subject: [PATCH 09/13] Notes from MK's PCB livestream - avoid non-circular holes in footprints whenever possible; some fabs charge more for ovals - make power connection traces larger; MK uses .6mm this means from the centerline of the knurl properties.
