Multi-pole rotary switch with 12 positions D 4 rotary switches are actually 2p6t, which means only six different step counts are available until the replacement arrives Wiring SW15 (once/stop) and cascade out is easier done via skywiring; only one tl074 and support components, so tiny PCB should be the same, see datasheet: https://www.mouser.com/datasheet/2/54/PTL-777483.pdf (page 4) 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 these is supposed to be more stable than MK's, but it's unclear whether JLCPCB is still the best option. This page is to tumblr, but there's a url in the documentation and/or other materials provided with the setscrew hole, providing sufficient thread length where thin stems walls don't. * @todo Add support for cutouts that leave spokes between the hub and circumference. * @todo Adjust $fn based on the https://www.onsemi.com/pub/Collateral/NCP115-D.PDF Panasonic HQFN-16, 4x4x0.85mm (https://industrial.panasonic.com/content/data/SC/ds/ds7/c0/PKG_HQFN016-A-0404XZL_EN.pdf Panasonic HSON-8, 8x8x1.25mm (https://industrial.panasonic.com/content/data/SC/ds/ds7/c0/PKG_HSON008-A-0808XXI_EN.pdf QFN, 12 Pin (https://ww1.microchip.com/downloads/aemDocuments/documents/APID/ProductDocuments/DataSheets/MIC2207-2MHz-3A-PWM-Buck-Regulator-DS20006470A.pdf#page=22), generated with kicad-footprint-generator ipc_noLead_generator.py WQFN, 14 Pin (https://www.st.com/resource/en/datasheet/lsm6ds3tr-c.pdf), generated with kicad-footprint-generator ipc_noLead_generator.py DHVQFN, 20 Pin (JEDEC MO-153 Var ED https://www.jedec.org/document_search?search_api_views_fulltext=MO-153), generated with kicad-footprint-generator Soldered wire connection with feed through strain relief, for 2 times 1.5 mm² wires, reinforced insulation, conductor diameter 0.9mm, outer diameter 2.7mm, size source Multi-Contact FLEXI-E 2.5 (https://ec.staubli.com/AcroFiles/Catalogues/TM_Cab-Main-11014119_(en)_hi.pdf), bend radius 3 times 0.1 mm² wires, basic insulation, conductor diameter 1.25mm, outer diameter 3.5mm, size 45.5x7.6mm^2, drill diamater 1.3mm, pad diameter 3mm, 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 Hirose FH12, FFC/FPC connector, FH12-11S-0.5SH, 11 Pins (http://www.molex.com/pdm_docs/sd/559350210_sd.pdf), generated with kicad-footprint-generator Molex CLIK-Mate series connector, 501331-0307 (http://www.molex.com/pdm_docs/sd/5013310207_sd.pdf), generated with kicad-footprint-generator Samtec HLE .100" Tiger Beam Cost-effective Single Beam Socket Strip, HLE-121-02-xxx-DV-A, 21 Pins per row (https://www.hirose.com/product/en/products/FH12/FH12-24S-0.5SH(55)/), generated with kicad-footprint-generator Molex Mini-Fit Jr. Power Connectors, 42819-62XX, With thermal vias in pads, 5 Pins per row (http://www.molex.com/pdm_docs/sd/439151404_sd.pdf), generated with kicad-footprint-generator Molex CLIK-Mate series connector, 502585-0770 (http://www.molex.com/pdm_docs/sd/5025850270_sd.pdf), generated with kicad-footprint-generator Molex PicoBlade series connector, B15B-EH-A (http://www.jst-mfg.com/product/pdf/eng/eEH.pdf), generated with kicad-footprint-generator Samtec HLE .100" Tiger Beam Cost-effective Single Beam Socket Strip, HLE-142-02-xxx-DV-BE-A, 42 Pins per row (http://www.molex.com/pdm_docs/sd/460071105_sd.pdf), generated with kicad-footprint-generator ipc_noLead_generator.py QFN, 32 Pin (http://www.analog.com/media/en/package-pcb-resources/package/pkg_pdf/ltc-legacy-qfn/QFN_32_05-08-1693.pdf), generated with kicad-footprint-generator JST ZE series connector, DF3EA-14P-2H (https://www.hirose.com/product/document?clcode=CL0543-0332-0-51&productname=DF3EA-5P-2H(51)&series=DF3&documenttype=2DDrawing⟨=en&documentid=0001163317), generated with kicad-footprint-generator connector wire 0.75sqmm strain-relief Soldered wire connection, for 6 times.
