Smart Relay Design Requirements
Worked for 10 sec
I’ll check the project BOM and availability metadata, especially LCSC/JLCPCB fields, then report which parts are ready and which need sourcing replacements.

Assuming you mean LCSC: No, not all components are currently available/assigned from LCSC.
LCSC-available in current BOM
- KF128-5.08-2P-AA terminals — LCSC stock shown
- LMR16030SDDAR buck regulator — LCSC stock shown
- ESP32-S3-WROOM-1U-N16R8 — LCSC stock shown
- AP2112K-3.3TRG1 — LCSC stock shown
- TPS2051CDBVR — LCSC stock shown, but wrong for requirement because it is 0.5 A class and USB host target is 1 A
- STTH212S diode — LCSC stock shown
- SMBJ30CA TVS — LCSC part metadata present
- ISO6741 digital isolator — no LCSC SKU/stock shown
- ISO1212 isolated DI receivers — no LCSC SKU/stock shown
- ISOW1044 isolated CAN transceiver — no LCSC SKU/stock shown
- AD7329 ADC — no LCSC SKU/stock shown
- JQC-3F-1C-24VDC relay — no LCSC SKU/stock shown
- USB4105-GF-A USB-C connector — LCSC stock shown as 0
- ULN2003A — LCSC stock shown as 0 for current selected part
- Generic resistors/capacitors/inductor — not assigned to specific LCSC MPNs yet
- Solenoid FET Driver 3.3V blocks — not production BOM-ready as discrete LCSC parts
So the design is not yet LCSC/JLCPCB procurement-ready. Next step should be a sourcing pass to replace/assign LCSC-stocked MPNs for the unavailable ICs, relay, USB connector, passives, inductor, and 1 A USB power switch.
Run sourcing pass
Fix USB switch
Assign passives
Resolve production risks
Check relay options
Waiting for input
