BackRotary encoder, EC12E... With switch, horizontal shaft, https://www.bourns.com/docs/product-datasheets/pec12r.pdf Bourns rotary encoder, EC12E... With switch, vertical shaft, mounting holes distance 63.5mm Hirose FH12, FFC/FPC connector, FH12-34S-0.5SH, 34 Pins per row (https://www.molex.com/pdm_docs/sd/430450221_sd.pdf), generated with kicad-footprint-generator ipc_noLead_generator.py XDFN4 footprint (as found on the top surface of the plastic walls. Clf_wall = 2; // surface("FireballSpellSmall.png", center=true, invert=false); More experimentation with panel title fonts } STLs, 10hp version, others schematics width_mm=60; height=10; More experimentation with panel title fonts Untested hardware and software — Do not assume anything works! Repo uses submodules aoKicad and Kosmo_panel, which provide needed libaries for KiCad. To clone: submodules 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 * [How to use](Docs/use.md 96f746fa2d Final tweaks, version submitted to JLCPCB on 20240124 Final tweaks, version submitted to JLCPCB on 20240124 3d279dd88c Finish schematic, add PDF' (#2) from schematic into main 1705ad98fb Put title box in PDF export' (#4) from schematic by Eeschema 5.1.10-88a1d61d58~90~ubuntu20.04.1 Component Count: 76 Refs C2, C5, C6, C8, C9 | 1 | Conn_01x07 | \*(optional) SIP socket, 2.54 mm, 1x2 (see [build notes](build.md)) | | | R4, R12, R13 | 3 | A1M | Potentiometer | | | | | | | | R30 | 1 nF | Unpolarized capacitor | | C2 | 1 | 1uF | Film capacitor | | | J9 | 1 | TL074 | Quad operational amplifier, DIP-14
