Do not buy/populate R404, R408 or J302 for this variant. U202 is separate. PCB solder jumpers are copper, not purchased components.

Use the carrier table for PCB components

  • For PCBA, JLC sources the 43 fitted carrier pieces from the uploaded BOM. You do not need a second loose set.
  • For hand assembly, filter Carrier parts and buy the listed quantities. All C-codes link to their supplier listing.

Buy the separate system parts

  • Luckfox Pico Mini; verify SD boot compatibility. Pro/Max/Pi modules are different targets.
  • Exact 2.8-inch ST7789 bare 40-pin FPC panel; compatible SC3336 camera/ribbon; case; microSD; regulated 5 V USB power.
  • Add a contact SeedKeeper for storage or Satochip for on-card signing. Cards are optional for ordinary host signing.

Confirm the unresolved substitutions before checkout

  • HS280S010B / C2939938 is not a drop-in LCD: it is a 14-pin module.
  • Do not use a bottom-contact LCD connector in place of J401’s selected top-contact part.
  • A case or retail carrier may have a different revision/reader suffix from this variant. Confirm its bundle contents and firmware configuration.
