BackWorks! Repo uses submodules aoKicad and Kosmo\_panel. To clone: submodules avoid non-circular holes in footprints whenever possible; some fabs charge more for ovals avoid non-circular holes in footprints whenever possible; some fabs charge more for ovals - make power connection traces larger; MK uses a CA3080 OTA, an expensive and rare chip these days ($3/ea on amazon, maybe fakes) VCA MK's VCA Probably a straightforward build: one op-amp, four transistors and some example modules schematic start, and some example modules main 5a4e89eea6 Add position for resistor between coarse and +12V, value unknown Align panel to integer pseudo-origin, remove testing text, decrease title label font so we don't lose it bd1352a047 Fix annoyance of 2x05 IDC header THT 2x01 1.00mm double row surface-mounted straight pin header, 2x38, 2.00mm pitch, double rows latches, mounting holes, https://docs.google.com/spreadsheets/d/16SsEcesNF15N3Lb4niX7dcUr-NY5_MFPQhobNuNppn4/edit#gid=0 Through hole angled pin header, 2x16, 1.27mm pitch, double cols (https://gct.co/files/drawings/bc085.pdf), script generated Through hole angled socket strip SMD 1x21 2.00mm single row style1 pin1 left Surface mounted pin header THT 2x26 1.00mm double row surface-mounted straight pin header, 2x02, 1.27mm pitch, double rows Through hole straight socket strip, 1x28, 1.00mm pitch, 2.0mm pin length, single row Through hole angled socket strip, 2x24, 2.00mm pitch, 6.35mm socket length, single row style2 pin1 right Through hole angled pin header, 1x36, 1.27mm pitch, single row Through hole vertical IDC box header, 2x06, 2.00mm pitch, double rows Surface mounted socket strip SMD 1x24 2.54mm single row Surface mounted pin header SMD 2x04 1.00mm double row Through hole IDC header, 2x05, 2.54mm pitch, 8.51mm socket length, single row (from Kicad 4.0.7!), script generated Surface mounted pin header THT 2x21 1.27mm double row surface-mounted straight socket strip, 2x29, 2.00mm pitch, 4.2mm pin length, single row male, vertical entry, strain relief clip Harwin LTek Connector, 8 pins, pitch 3.81mm, size 18.9x7.3mm^2, drill diamater 1.3mm, pad diameter 2.5mm, see http://cdn-reichelt.de/documents/datenblatt/C151/RND_205-00056_DB_EN.pdf, script-generated.
