Starfish BOM issues:

  • C203, C1411, C1511, C1611 Capacitor 865080653016 seems to be too big for the footprint | suggestion: same as C5, C22 on Jellyfish EEE-TQV101XAP
  • D401 - D404 different mpn, some for 5V instead of 3V3 | suggestion: should all be the same PESD3V3U1UA,115
  • F201 fuse should be part of the schematic so it is included in the BOM | no suggestion: forgot to buy one :(

  • R202, R1003, R1103, R1303, R1703 footprint is 0402 mpn is for 0603 | suggestion: AC0402FR-075K1L
