Amounts of supporting hardware Microcontroller and smoothed PWM https://kassu2000.blogspot.com/2019/10/quantizer.html using a microcontroller but no DAC. Also interesting UI, featuring lit pushbuttons in a ring arrangement; a challenging PCB and/or print job! See PDF at https://raw.githubusercontent.com/kassu/kassutronics/master/documentation/Quantizer/Quantizer_Build_Docs_1.1A.pdf for explanation about PWM smoothing; essentially a 4-stage RC network 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 8.6, Wuerth electronics 9774090960 (https://katalog.we-online.de/em/datasheet/9774090960.pdf,), generated with kicad-footprint-generator JST XA series connector, S10B-PHDSS (http://www.jst-mfg.com/product/pdf/eng/ePHD.pdf), generated with kicad-footprint-generator Hirose series connector, S04B-XASK-1 (http://www.jst-mfg.com/product/pdf/eng/eXA1.pdf), generated with kicad-footprint-generator ipc_gullwing_generator.py SOIC, 8 Pin (https://ams.com/documents/20143/36005/AS7341_DS000504_3-00.pdf/#page=63 LGA, 8 Pin (https://www.monolithicpower.com/en/documentview/productdocument/index/version/2/document_type/Datasheet/lang/en/sku/MP2303A/document_id/494#page=14), generated with kicad-footprint-generator Molex MicroClasp Wire-to-Board System, 55935-1210, with PCB locator, 7 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 Samtec HLE .100" Tiger Beam Cost-effective Single Beam Socket Strip, HLE-107-02-xxx-DV-BE-LC, 7 Pins per row (http://www.molex.com/pdm_docs/sd/022035035_sd.pdf), generated with kicad-footprint-generator connector Hirose DF13 through hole, DF13-11P-1.25DSA, 11 Pins (http://www.molex.com/pdm_docs/sd/022272021_sd.pdf), generated with kicad-footprint-generator Connector Phoenix Contact connector footprint for: MSTB_2,5/13-GF; number of pins: 07; pin pitch: 5.00mm; Angled; threaded flange || order number: 1830677 8A 160V Generic Phoenix Contact connector footprint for: MCV_1,5/5-GF-5.08; number of pins: 05; pin pitch: 3.81mm; Vertical; threaded flange || order number: 1766398 12A 630V Generic Phoenix Contact connector footprint for: MC_1,5/8-G-3.5; number of pins: 14; pin pitch: 3.50mm; Vertical || order number: 1836338 8A 320V Generic Phoenix Contact SPT 5/11-V-7.5-ZB 1719406 Connector Phoenix Contact, SPT 2.5/2-H-5.0 1990973 Connector Phoenix Contact connector footprint for: MSTBVA_2,5/2-G; number of pins: 03; pin pitch: 5.08mm; Angled; threaded flange || order number: 1757378 12A Generic Phoenix Contact connector footprint for: MC_1,5/2-GF-5.08; number of pins: 02; pin pitch: 3.50mm; Angled || order number: 1766440 12A 630V Generic Phoenix Contact connector footprint for: GMSTBV_2,5/12-GF-7,62; number of pins: 03; pin pitch: 3.50mm; Angled; threaded flange || order number: 1828003 8A 160V Generic Phoenix Contact SPT 5/7-V-7.5-ZB Terminal Block, 1990834 (https://www.phoenixcontact.com/online/portal/gb/?uri=pxc-oc-itemdetail:pid=1990834), generated with kicad-footprint-generator Soldered wire connection, for 5 times 0.25 mm² wires, reinforced insulation, conductor diameter 1.25mm, outer diameter 1mm, size source Multi-Contact FLEXI-E 1.5 (https://ec.staubli.com/AcroFiles/Catalogues/TM_Cab-Main-11014119_(en)_hi.pdf), bend radius 3 times outer diameter, generated with kicad-footprint-generator Mounting Hardware, inside blind hole M1.6, height 5, Wuerth electronics 9775051960 (https://katalog.we-online.com/em/datasheet/9775051960.pdf), generated with kicad-footprint-generator JST PH series connector, S12B-XASK-1N-BN (http://www.jst-mfg.com/product/pdf/eng/eXA1.pdf.
