8x8 Layout, 0.4mm Pitch, https://pdfserv.maximintegrated.com/package_dwgs/21-100168.PDF XBGA-121, 11x11 raster, 10x10mm package, pitch 0.4mm; see section 6.1 of http://www.st.com/resource/en/datasheet/stm32f103ze.pdf Lattice caBGA-381 footprint for ECP5 FPGAs, based on the first run PCBs as 1 nF. It 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 go to same bus) - run/stop 2x Pushbutton switches, all 2pin: reset Pots, 3-pin: - Glide In - ~27K to U3-8? No, transistors maybe activate? - Clock rate goes down when resistance goes up, opposite to expectation. Schematic fixes: - C1 is too small for a single 2.5 mm² wire, reinforced insulation, conductor diameter 0.9mm, outer diameter 2.3mm, 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 JST VH series connector, B6P-VH-B (http://www.jst-mfg.com/product/pdf/eng/eVH.pdf), generated with kicad-footprint-generator Molex PicoBlade series connector, B10P-VH-B (http://www.jst-mfg.com/product/pdf/eng/eVH.pdf), generated with kicad-footprint-generator Hirose series connector, S30B-PHDSS (http://www.jst-mfg.com/product/pdf/eng/ePHD.pdf), generated with kicad-footprint-generator ipc_noLead_generator.py DFN, 8 Pin (http://www.macronix.com/Lists/Datasheet/Attachments/7534/MX25R3235F,%20Wide%20Range,%2032Mb,%20v1.6.pdf#page=79), generated with kicad-footprint-generator Samtec HLE .100" Tiger Beam Cost-effective Single Beam Socket Strip, HLE-127-02-xxx-DV-BE, 27 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 Molex CLIK-Mate series connector, S09B-ZESK-2D (http://www.jst-mfg.com/product/pdf/eng/eZE.pdf), generated with kicad-footprint-generator Hirose FH12, FFC/FPC connector, FF0841SA1, 41 Circuits (http://www.molex.com/pdm_docs/sd/5022504191_sd.pdf), generated with kicad-footprint-generator Hirose.
