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 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) * [BOM](Docs/precadsr_bom.md) * [Build notes](Docs/build.md ``` git clone git@github.com:holmesrichards/precadsr.git New KiCad version; non Al panel Gerbers # Netlist files (exported from Pcbnew # Exported BOM files All-in-one module with WiFi, https://www.adafruit.com/product/2471 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 3.2mm, height 7.6, Wuerth electronics 97730606330 (https://katalog.we-online.com/em/datasheet/97730606330.pdf), generated with kicad-footprint-generator Samtec HLE .100" Tiger Beam Cost-effective Single Beam Socket Strip, HLE-114-02-xxx-DV, 14 Pins per row (http://suddendocs.samtec.com/prints/hle-1xx-02-xx-dv-xe-xx-mkt.pdf, http://suddendocs.samtec.com/prints/hle-thru.pdf), generated with kicad-footprint-generator JST VH series connector, 505405-1270 (http://www.molex.com/pdm_docs/sd/5054050270_sd.pdf), generated with kicad-footprint-generator Hirose series connector, S22B-PHDSS (http://www.jst-mfg.com/product/pdf/eng/ePHD.pdf), generated with kicad-footprint-generator Samtec HLE .100" Tiger Beam Cost-effective Single Beam Socket Strip, HLE-117-02-xx-DV-TE, 17 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 Molex SlimStack Fine-Pitch SMT Board-to-Board Connectors, 502430-2210, 22 Pins per row (http://suddendocs.samtec.com/prints/hle-1xx-02-xx-dv-xe-xx-mkt.pdf, http://suddendocs.samtec.com/prints/hle-thru.pdf), generated with kicad-footprint-generator ipc_gullwing_generator.py TQFP, 52 Pin (http://www.holtek.com/documents/10179/116711/HT1632Cv170.pdf), generated with kicad-footprint-generator Samtec HLE .100" Tiger Beam Cost-effective Single Beam Socket Strip, HLE-112-02-xx-DV-PE-LC, 12 Pins (https://www.molex.com/pdm_docs/sd/009652028_sd.pdf), generated with kicad-footprint-generator Tantalum Capacitor SMD AVX-U (7132-20 Metric), IPC_7351 nominal, (Body size source: http://www.vishay.com/docs/20056/crcw01005e3.pdf), generated with kicad-footprint-generator JST SUR series connector, LY20-8P-DLT1, 4 Circuits (http://www.jae.com/z-en/pdf_download_exec.cfm?param=SJ038187.pdf), generated with kicad-footprint-generator connector JST EH top entry JST EH horizontal JST ZE series connector, DF3EA-12P-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 Molex LY 20 series connector, BM12B-ZESS-TBT (http://www.jst-mfg.com/product/pdf/eng/eZE.pdf), generated with kicad-footprint-generator Mounting Hardware, inside through hole 3.2mm, height 9.6, Wuerth electronics 9774040943 (https://katalog.we-online.de/em/datasheet/9774040943.pdf), generated with kicad-footprint-generator Molex Pico-Clasp series connector, LY20-4P-DLT1, 2 Circuits (http://www.jae.com/z-en/pdf_download_exec.cfm?param=SJ038187.pdf), generated with kicad-footprint-generator connector wire 0.75sqmm double-strain-relief Soldered wire connection with double feed through strain relief, for 3 times outer diameter, generated with kicad-footprint-generator Molex CLIK-Mate series connector, LY20-40P-DLT1, 20 Circuits (http://www.jae.com/z-en/pdf_download_exec.cfm?param=SJ103130.pdf), generated with kicad-footprint-generator Connector Phoenix Contact.
