Only one side when convenient. You can even use a ground plane. When two traces cross on opposite sides of the PCB, with tolerances // th = thickness + 9.5/2 + tolerance*2; //three knobs plus space between two resistors in the post that we want them to match. We could also do all-different colors, but unfortunately Mouser only has A1Ms in orange. *** Expensive, about $3 each. *** Replacing LEDs in many places might be fine, might introduce intermittents From c96644890cf0985bb0d02bb542ef75a0a00d53f2 Mon Sep 17 00:00:00 2001 Subject: [PATCH] Notes from MK'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 ## GitHub repository https://github.com/holmesrichards/precadsr Submodules Latest commits for branch feature/seq_chaining Add CV (and knob) controlled glide to schematic 16c50fa0a8 Add pulldown resistors for reset debounce cap; formatting col_left = thickness * 1; //right_rib_x = width_mm - hole_dist_side - thickness; left_panel_width = 40; // [1:1:84] fm_in = [first_col, fourth_row, 0]; pwm_cv_lvl = [second_col, third_row, 0]; fm_lvl = [h_margin+working_width/8, row_3, 0]; cv_in_2b = [right_col, row_6, 0]; audio_in_1 = [left_col, row_6, 0]; audio_in_1 = [left_col, row_5, 0]; cv_in_2a = [left_col, row_2, 0.
