BackNeeded. Subject: [PATCH 06/18] tracks the ratsnest and compactifies the power safety block and into any non-high-impedence connections; that is, fat traces to chip power, but not some kind of odd LFO. * PCB layout: [front](Docs/precadsr_layout_front.pdf), [back](Docs/precadsr_layout_back.pdf) * [BOM](Docs/precadsr_bom.md) * [Build notes](Docs/build.md ## GitHub repository * [https://github.com/holmesrichards/precadsr](https://github.com/holmesrichards/precadsr ## Submodules This repo uses submodules aoKicad and Kosmo_panel directories.
