Step // 1 for manual step (featuring debouncing!), sequencer cascading, basic glide (for portamento), attack decay sustain release envelope generator synth module. Layout and panel are Kosmo format. * [Schematic](Docs/precadsr.pdf) * PCB layout: make power connection traces larger; MK uses .6mm -- this means from the centerline of the rail + a safety margin // margins from edges h_margin = hole_dist_side + thickness; Experimenting with more panel layout # Kassutronics Precision ADSR build notes Change C13 to 10 nF | Unpolarized capacitor | | C1 | 1 nF | Unpolarized capacitor | | | R6, R8 | 2 pin Molex header 2.54 mm spacing Q1, Q2, Q3 | 3 | A1M | **Potentiometer, 9 mm vertical board mount OR: | | | | Screws and spacers (see build notes) 1 SIP socket, 2.54 mm, 1x10 | | Tayda | A-962 | | C2 | 1 | 2_pin_Molex_connector | 2 | 1N5817 | Schottky diode | | | S3 | 1 | LED | Light emitting diode, 5 mm x 0.3 mm body (https://assets.nexperia.com/documents/package-information/SOD962-2.pdf https://www.nexperia.com/packages/SOD962-2.html Diode SMPA (DO-221BC), https://www.vishay.com/docs/87659/v8pa10.pdf Single phase, Bridge rectifier, 28.614x28.614mm, case KBPC_T(FP), https://www.diodemodule.com/bridge-rectifier/kbpc/kbpc1501t.pdf Single phase, Bridge Rectifier, 28.55x28.55mm, case KBPC_W(WP), https://www.diodemodule.com/bridge-rectifier/kbpc/kbpc15005w.pdf 128x32 LCD with RGB backlight https://www.newhavendisplay.com/specs/NHD-C12832A1Z-FSRGB-FBW-3V.pdf EPCOS/TDK Electronics/Qualcomm DCC6c SAW filter package - 1.4x1.1 mm Body; (see https://www.murata.com/~/media/webrenewal/support/library/catalog/products/filter/rf/p73e.ashx?la=en-gb 5-pin filter package - 1.4x1.1 mm Body; (see https://global.kyocera.com/prdct/electro/product/pdf/sf14_tdlte.pdf 0.5A, 250VAC, 50/60Hz line filter (https://filtercon.com.pl/wp-content/uploads/2019/07/Karta-katalogowa-FP-12-1.pdf Mini-Circuits Filter SMD 1206 (3216 Metric), square (rectangular) end terminal, IPC_7351 nominal.
