Synth module. Layout and panel are Kosmo format. * [Schematic](Docs/precadsr.pdf) * 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 7.5mm holes, not 6mm - alpha pots - 9.8mm, +2mm rotary - 11.5mm, +3.5mm -- biggest by far, maybe 12.6mm? SR2511 series are 11.43? Maybe more? Distance between pcb and front panel: mini toggle: 4mm above panel, tight but possible mini toggle: 2.5mm above panel, ample thunkicons: probably too tight; could work with printed spacers mini toggle: ample space above 11.75mm (existing 1p12t rotaries, use 11.25mm holes to PCB edge 15.979999999999999mm, see https://disti-assets.s3.amazonaws.com/tonar/files/datasheets/16730.pdf 44-pin D-Sub connector, horizontal/angled (90 deg), THT-mount, female, pitch 2.77x2.84mm, pin-PCB-offset 4.9399999999999995mm, distance of mounting holes 47.1mm, distance of mounting holes to PCB edge 10.889999999999999mm, see https://disti-assets.s3.amazonaws.com/tonar/files/datasheets/16730.pdf 25-pin D-Sub connector horizontal angled 90deg THT male pitch 2.41x1.98mm pin-PCB-offset 3.0300000000000002mm mounting-holes-distance 33.3mm mounting-hole-offset 33.3mm 15-pin D-Sub connector, horizontal/angled (90 deg), THT-mount.
