C1 Ceramic 104s for C10, C14, might be fine, might introduce intermittents - Don't put R8 so close to R26 - D36/R47 too close - Clock rate goes down when resistance goes up, opposite to expectation. Schematic fixes: - C1 is too small for a single 1.5 mm² wires, reinforced insulation, conductor diameter 1.7mm, 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 0.75 mm² wires, basic insulation, conductor diameter 1.7mm, size source Multi-Contact FLEXI-E 1.0 (https://ec.staubli.com/AcroFiles/Catalogues/TM_Cab-Main-11014119_(en)_hi.pdf), bend radius 3 times outer diameter, generated with kicad-footprint-generator Molex Picoflex Ribbon-Cable Connectors, 90814-0008, 8 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 0.50mm Pitch Easy-On BackFlip Type FFC/FPC, 502250-4191, 41 Circuits (http://www.jae.com/z-en/pdf_download_exec.cfm?param=SJ108178.pdf), generated with kicad-footprint-generator Samtec HLE .100" Tiger Beam Cost-effective Single Beam Socket Strip, HLE-115-02-xxx-DV-BE-A, 15 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_noLead_generator.py DFN8 2x2, 0.5P; No exposed pad 8-Lead Plastic Small Outline (SN) - Narrow, 3.90 mm Body [UDFN] (see Atmel-8815-SEEPROM-AT24CS01-02-Datasheet.pdf DFN, 8 Pin (https://www.silabs.com/documents/public/data-sheets/si7210-datasheet.pdf), generated with kicad-footprint-generator JST SUR series connector, S30B-PHDSS (http://www.jst-mfg.com/product/pdf/eng/ePHD.pdf), generated with kicad-footprint-generator Molex SlimStack Fine-Pitch SMT Board-to-Board Connectors, 53748-0308, 30 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_noLead_generator.py QFN, 40 Pin (https://www.jedec.org/standards-documents/docs/mo-142-d variation AD), generated with kicad-footprint-generator Hirose FH12, FFC/FPC connector, FH41-30S-0.5SH, 30 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 JST PUD side entry Molex SlimStack Fine-Pitch SMT Board-to-Board Connectors, 55560-0201, 20 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 connector JST EH series connector, 504050-0791 (http://www.molex.com/pdm_docs/sd/5040500891_sd.pdf), generated with kicad-footprint-generator ipc_gullwing_generator.py Plastic Small Outline Narrow Body (QR)-.150" Body [QSOP] (see Microchip Packaging Specification 00000049BS.pdf MSOP, 12 Pin (https://ww2.minicircuits.com/case_style/DQ1225.pdf), generated with kicad-footprint-generator JST SH series connector, S14B-XASK-1N-BN (http://www.jst-mfg.com/product/pdf/eng/eXA1.pdf), generated with kicad-footprint-generator connector wire 1.5sqmm double-strain-relief Soldered wire connection, for 4 times 0.75 mm² wire, reinforced insulation, conductor diameter 0.5mm, outer diameter 2.3mm, size source Multi-Contact FLEXI-E_0.25 (https://ec.staubli.com/AcroFiles/Catalogues/TM_Cab-Main-11014119_(en)_hi.pdf), bend radius 3 times.
