BackLivestream 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 apply smooth = 20; // tweak on this and/or Hagiwo's quantizer, if going digital ** https://note.com/solder_state/n/nde97a0516f03 and https://www.youtube.com/watch?v=op_DhPr2goc ** arduino nano clone (atmega 328p), 12-bit dac (mcp4726) and small amounts of supporting hardware Microcontroller and smoothed PWM https://kassu2000.blogspot.com/2019/10/quantizer.html using a setscrew).

Maybe enlarge footprint if needed.
