Added schmancy pcb for v1 front panel and pcb into different files Add footprint items for panel holes; separate panel and pcb into different files Add a front-panel PCB "net_color_mode": 1, "opacity": { More tweaks after pro review } ], "meta": { "version": 3 }, "net_colors": null, "netclass_assignments": null, updates to rev 2 beta by adding +5V, and both trigger/gate and CV lines? **UI:** - 3 x 3 mm, 0.5 mm pitch, ultra thin SMD package; 3 leads; body: 4.3x6.1x0.43mm, https://www.vishay.com/docs/95570/to-277asmpc.pdf 3-pin TSOT23 package, http://cds.linear.com/docs/en/packaging/SOT_8_05-08-1637.pdf Texas Instrument DRT-3 1x0.8mm Pitch 0.7mm Texas Instruments, DSBGA, area grid, YBJ0008 pad definition, 0.704x1.054mm, 6 Ball, 2x3 Layout, 0.35mm Pitch, http://www.latticesemi.com/view_document?document_id=213 Analog Devices (http://www.analog.com/media/en/technical-documentation/data-sheets/ADL5542.pdf LFCSP 8pin Pitch 0.5mm, http://www.analog.com/media/en/package-pcb-resources/package/pkg_pdf/lfcspcp/cp_8_6.pdf LFCSP 8pin thermal pad TQFP64 7x7, 0.4P CASE 932BH (see ON Semiconductor 932BB.PDF 144-Lead Plastic Thin Quad Flatpack - 10x10x2.5mm Body (http://www.onsemi.com/pub/Collateral/122BK.PDF PQFP80 14x20 / QIP80E CASE 122BS (see ON Semiconductor 932BB.PDF 144-Lead Plastic Thin Quad Flat, No Lead Package (UC) - 3x3x0.5 mm Body [DFN] (see Microchip Packaging Specification 00000049BS.pdf 80-Lead.- File edits README.md file - Before producing, confirm.
