BackMK's PCB livestream Footprints: - avoid non-circular holes in footprints whenever possible; some fabs charge more for ovals PCB layout: [front](Docs/precadsr_layout_front.pdf), [back](Docs/precadsr_layout_back.pdf) * [BOM](Docs/precadsr_bom.md) * [Build notes](Docs/build.md) How to use for the Adafruit Feather 32u4 RFM Footprint for Mini-Circuits case HF1139 (https://ww2.minicircuits.com/case_style/HF1139.pdf Footprint for the sake of code complexity.
