Every carrier line identified, plus the parts needed to finish the device.
Your shopping list
The eight-pin pill is the current build: design & display pinout · header and support assembly. Select the standard FPC reference only when building that separate board.
For PCBA, JLC buys the SMT components. Buy the separate system parts yourself; switch to Carrier / PCBA to inspect the exact values, ratings and quantities.

R404, R408 and J302 remain DNP. U202 is separate. PCB solder jumpers are copper, not purchased parts.
Use the carrier table for PCB components
- For pill PCBA, JLC sources 43 fitted SMT placements from the matching BOM; do not buy a second loose set.
- The table defaults to the eight-pin pill carrier. Select Standard FPC only when building that separate board. Values, ratings and quantities remain visible.
Buy the separate system parts
- Luckfox Pico Mini with compatible microSD boot and matching SC3336 camera/ribbon.
- HOTHMI HTM-TFT028A16-SPI, no-touch, using its J1 eight-pin 2.54 mm row; socket/header strips, 12 mm supports and short screws.
- microSD, one regulated 5 V USB supply and a new pill enclosure. Add a compatible contact card only if using the smartcard features.
Confirm the exact module and hardware
- The LCD is a 3.3 V module. Match the saved drawing and J1 row; do not buy the former Pico-format display or a bare FPC panel for this PCB.
- Carrier header numbering runs opposite module J1 numbering. Verify all signals and the specified connector heights before soldering.
- The old enclosure does not fit. Confirm supports, screw engagement, camera cable path and button plungers.
