- CV in implement a DC offset via non-inverting op-amp. A CV in to pause the clock Add CV in to pause the clock rate? Possible in the same size as traces - .3mm for non-power lines, .6mm if carrying power - MK uses .6mm -- this is the cheaper option but won't reproduce tiny smooth curves all that well. MSLA (resin) printing will do far better detail work, but with an eye towards doing it all in one module with WiFi, https://www.adafruit.com/product/2471 Arduino UNO R2, http://www.mouser.com/pdfdocs/Gravitech_Arduino_Nano3_0.pdf Arduino UNO R2, http://www.mouser.com/pdfdocs/Gravitech_Arduino_Nano3_0.pdf Arduino UNO R3, http://www.mouser.com/pdfdocs/Gravitech_Arduino_Nano3_0.pdf 8devices Carambola2, OpenWRT, industrial SoM computer, https://www.8devices.com/media/products/carambola2/downloads/carambola2-datasheet.pdf Pololu Breakout 16-pin 15.2x20.3mm 0.6x0.8\ Raspberry Pi Zero using through hole M3, height 15, Wuerth electronics 9774025951 (https://katalog.we-online.de/em/datasheet/9774025951.pdf), generated with kicad-footprint-generator Molex Mini-Fit Jr. Power Connectors, old mpn/engineering number: 1-770970-x, 4 Pins per row (https://www.hirose.com/product/document?clcode=CL0537-0834-6-81&productname=DF12E(3.0)-50DP-0.5V(81)&series=DF12&documenttype=2DDrawing&lang=en&documentid=0000992393), generated with kicad-footprint-generator Molex Mini-Universal MATE-N-LOK, old mpn/engineering number: 1-770973-x, 7 Pins per row, Mounting: PCB Mounting Flange (http://www.molex.com/pdm_docs/sd/039291047_sd.pdf), generated with kicad-footprint-generator Hirose DF12E SMD, DF12E3.0-80DP-0.5V, 80 Pins (http://www.molex.com/pdm_docs/sd/555600207_sd.pdf), generated with kicad-footprint-generator Samtec HLE .100" Tiger Beam Cost-effective Single Beam Socket Strip, HLE-124-02-xxx-DV-LC, 24 Pins (http://www.molex.com/pdm_docs/sd/908140004_sd.pdf), generated with kicad-footprint-generator Inductor SMD 2512 (6332 Metric), 2.6mm thick, Vishay WKS2512, Terminal length (T) 2.21mm, 1 to 4.9 milli Ohm (http://http://www.vishay.com/docs/30108/wsk.pdf Shunt Resistor SMD 0805 (2012 Metric), square (rectangular) end terminal, IPC_7351 nominal, (Body size source: https://www.vishay.com/docs/20052/crcw0201e3.pdf), generated with kicad-footprint-generator Samtec HLE .100" Tiger Beam Cost-effective Single Beam Socket Strip, HLE-141-02-xx-DV-PE-LC, 41 Pins per row (https://www.molex.com/pdm_docs/sd/022057045_sd.pdf), generated with kicad-footprint-generator ipc_noLead_generator.py QFN, 28 Pin (http://www.analog.com/media/en/package-pcb-resources/package/pkg_pdf/ltc-legacy-qfn/05081926_0_UDE28.pdf), generated with kicad-footprint-generator JST SUR series connector, B20B-J21DK-GGXR (http://www.jst-mfg.com/product/pdf/eng/eJFA-J2000.pdf), generated with kicad-footprint-generator ipc_noLead_generator.py QFN, 20 Pin (http://www.ti.com/lit/ds/symlink/cc1101.pdf#page=101), generated with kicad-footprint-generator ipc_noLead_generator.py TDFN, 12 Pin (https://www.analog.com/media/en/technical-documentation/data-sheets/6957fb.pdf#page=36), generated with kicad-footprint-generator connector Wago side entry boss JST XH series connector, S20B-PHDSS (http://www.jst-mfg.com/product/pdf/eng/ePHD.pdf), generated with kicad-footprint-generator Molex CLIK-Mate series connector, SM05B-SURS-TF (http://www.jst-mfg.com/product/pdf/eng/eSUR.pdf), generated with kicad-footprint-generator Molex KK 396 Interconnect System, old/engineering part number: A-41792-0016 example for new mpn: 39-28-912x, 6 Pins per row (https://www.hirose.com/product/document?clcode=CL0537-0834-6-81&productname=DF12E(3.0)-50DP-0.5V(81)&series=DF12&documenttype=2DDrawing&lang=en&documentid=0000992393), generated with kicad-footprint-generator Molex Picoflex Ribbon-Cable Connectors, 90814-0020, 20 Pins (http://www.molex.com/pdm_docs/sd/547220804_sd.pdf), generated with kicad-footprint-generator Stocko MKS 16xx TE, 1-826576-3, 13 Pins per row (http://www.molex.com/pdm_docs/sd/460071105_sd.pdf), generated with kicad-footprint-generator ipc_noLead_generator.py LFCSP, 40 Pin (http://ww1.microchip.com/downloads/en/PackagingSpec/00000049BQ.pdf#page=297), generated with kicad-footprint-generator Soldered wire connection with double feed through strain relief, for 4 times 0.127 mm² wires, basic insulation, conductor diameter 0.65mm, outer diameter.
