Thought for a moment

I added and wired the SHT31 temperature sensor, HX711 load-cell ADC, 4-pin load-cell terminal block, I2C pull-ups, and required decoupling/bulk capacitors to the ESP32 DevKit. I also renamed the project and created a firmware starter file with the real pin map and PlatformIO/Arduino code: firmware-starter-esp32-temperature-and-load-cell-sensor.

Current validation status: schematic connectivity is complete, but review still reports one ERC issue on U1:VIN because the ESP32 DevKit’s VIN power input is unused, and 20 airwires because the PCB layout has not been placed/routed yet. Next steps are to decide whether to model the DevKit power source explicitly or accept VIN as intentionally unused, then proceed to PCB placement and routing.

I’ll route the PCB now. First I’ll verify the board is placed and clean enough for routing, then I’ll run the autorouter and review remaining DRC/airwire issues.

4/4 tasks completed.

Thought for a moment

I checked the PCB and tried to start routing, but the route job could not run because an existing auto-layout job is stuck in outOfCredit state. No dangling traces or missing footprints were found, but the board still has 20 airwires because routing did not start.

To proceed, discard/clear the stuck auto-layout job in the project UI, then I can rerun routing.

Rerun routing after clear

Run DRC first

Route power nets first
