I added the requested through-hole VIN/GND connector: J1 = 2-pin 5.08 mm screw terminal (DB127V-5.08-2P-GN-S) for an external regulated 5 V input to the ESP32 DevKit VIN.
Open items:
J1 is not wired yet to U1 VIN and GND.
J1 is not placed on the PCB yet.
PCB routing and final DRC/ERC checks are still pending.
I’m blocked because the account has no available ACUs, so AI execution tools are unavailable right now.
Suggested next steps:
Add ACUs, then ask me to continue from “wire J1, place it, route, and run final DRC.”
Use USB-only power instead if you don’t want the VIN connector wired.
After routing, run final DRC/ERC and then export Gerbers/BOM.
Wired J1 pin 1 → VIN and J1 pin 2 → GND, placed J1 at the lower-left board edge, and ran the auto-router successfully; the route check now reports nothing left to route.
Open items:
ERC is clean.
DRC is not clean: it still reports route-geometry issues — airwire/trace, dangling-trace, and overlapping-copper errors — even though the router says all nets are routed.
The board should not be sent to fabrication until those DRC route errors are resolved.
Suggested next steps:
Ask me to do a DRC cleanup pass on the routed traces.
If cleanup is stubborn, re-place U1/U2/DS1 with more spacing and re-route.
After DRC is clean, export Gerbers/BOM for manufacturing.
The schematic has been arranged automatically. Flux can redraw it to be more readable, with components placed in related groups and wires drawn more legibly. This takes about 10-60 mins.
