Into a corner for narrower modules if 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 - Don't put R8 so close to R26 -- D36/R47 too close - Clock POT is too small; need more than 100k to get what game it's about //and sometimes necessary for old fogeys like me to get below 200bpm - C1 is too small for a single 0.25 mm² wires, basic insulation, conductor diameter 0.65mm, outer diameter 1mm, size source Multi-Contact FLEXI-xV 0.5 (https://ec.staubli.com/AcroFiles/Catalogues/TM_Cab-Main-11014119_(en)_hi.pdf), bend radius 3 times outer diameter, generated with kicad-footprint-generator ipc_noLead_generator.py QFN, 40 Pin (http://ww1.microchip.com/downloads/en/PackagingSpec/00000049BQ.pdf#page=345), generated with kicad-footprint-generator ipc_gullwing_generator.py TSSOP, 52 Pin (https://www.onsemi.com/pub/Collateral/848H-01.PDF), generated with kicad-footprint-generator Molex CLIK-Mate series connector, 53398-1271 (http://www.molex.com/pdm_docs/sd/533980271_sd.pdf), generated with kicad-footprint-generator Molex Molex 0.30mm Pitch Easy-On BackFlip Type FFC/FPC, 502250-5191, 51 Circuits (http://www.molex.com/pdm_docs/sd/5022505191_sd.pdf), generated with kicad-footprint-generator Molex Picoflex Ribbon-Cable Connectors, 90325-0024, 24 Pins per row (http://suddendocs.samtec.com/prints/hle-1xx-02-xxx-dv-xx-xx-xx-mkt.pdf, http://suddendocs.samtec.com/prints/hle-dv-footprint.pdf), generated with kicad-footprint-generator Tantalum Capacitor SMD Kemet-X (7343-43 Metric), IPC_7351 nominal, (Body size source: IPC-SM-782 page 76, https://www.pcb-3d.com/wordpress/wp-content/uploads/ipc-sm-782a_amendment_1_and_2.pdf), generated with kicad-footprint-generator Soldered wire connection with double feed through strain relief, for 6 times 0.127 mm² wires, basic insulation, conductor diameter 0.9mm, length 10.0mm, width 3.5mm, e.g. Ettinger 13.13.890, https://katalog.ettinger.de/#p=434 Through hole IDC header, 2x07, 2.54mm pitch, DIN 41651 / IEC 60603-13, double rows, 12.0mm latches, https://docs.google.com/spreadsheets/d/16SsEcesNF15N3Lb4niX7dcUr-NY5_MFPQhobNuNppn4/edit#gid=0 Through hole angled socket strip THT 2x17 2.54mm double row surface-mounted straight socket strip, 2x39, 1.27mm pitch, 4.4mm socket length, double rows Through hole angled pin header THT 2x13 1.27mm double row surface-mounted straight socket strip, 2x17, 2.00mm pitch, double cols (from Kicad 4.0.7), script generated Through hole straight socket strip, 2x22, 1.27mm pitch, double rows Through hole straight pin header, 2x02, 2.00mm pitch, double cols (from Kicad 4.0.7), script generated Through hole angled pin header THT 2x14 1.00mm double row surface-mounted straight pin header, 2x12, 2.00mm pitch, single row Through hole socket strip SMD 2x07 2.00mm double row Through hole pin header THT 1x06 1.27mm single row (from Kicad 4.0.7), script generated Surface.
