2-Position Screw Terminal Inquiry

flux

I can’t run auto-layout or modify the PCB right now because this account has no available ACUs, so AI execution features are unavailable.
So far in this session, the requested additions were clarified but not applied:
  • 2-position through-hole 5.08 mm screw terminal intended as J1.
  • WH-GM5 5G cellular LGA module intended as J2.
  • Nano-SIM slot intended as J3.
  • No confirmed schematic/layout mutations were completed in this session after those selections.
What remains:
  • Add J1, J2, and J3 to the schematic.
  • Wire WH-GM5 power, USB host interface, SIM interface, antenna/RF, reset/control, and required decoupling/protection.
  • Add or verify nano-SIM ESD protection and SIM pull-ups/caps per module datasheet.
  • Place the new components on the PCB.
  • Route required nets, especially USB differential pair and RF/SIM-sensitive traces.
  • Run DRC/ERC and layout checks.
Once ACUs are available again, I can analyze the current PCB state, decide whether placement, routing, or both are needed, and apply auto-layout automatically.

I can’t analyze or run auto-layout right now because this account has no available ACUs, so AI execution features are unavailable.
Current known state from this session:
  • J1 2-position through-hole 5.08 mm screw terminal was planned, but not added.
  • J2 WH-GM5 5G LGA module was planned, but not added.
  • J3 nano-SIM slot was planned, but not added.
  • No placement/routing changes were applied by me after those requests.
Remaining work once ACUs are available:
  • Inspect the schematic and PCB to confirm what is already placed/routed.
  • Add the missing J1/J2/J3 components if still desired.
  • Run placement if any components are unplaced or badly positioned.
  • Run routing if airwires remain.
  • Verify with DRC/ERC and fix any critical issues before manufacturing.
