Temperature and Humidity Sensor Node Design
Worked for 4 mins 41 sec
I continued until ACUs became unavailable. Completed: renamed/described the project, selected the architecture and parts, built the schematic with USB‑C input, TPS2595 eFuse protection, MP28301 3.3 V buck, ESP32‑C3 Wi‑Fi/BLE module, SHT41 sensor, USB data ESD, boot/reset, status LED, and created project files for the spec, power budget, firmware starter, bring-up plan, and regulatory notes.
Remaining work:
- Re-run ERC after the last cleanup step and resolve any remaining warnings.
- Confirm no-connect markings were applied for unused ESP32/J1 pins.
- Perform PCB placement/routing, especially ESP32 antenna keepout, buck layout, USB routing, and sensor thermal isolation.
- Run DRC/airwire checks after layout.
- Validate final TPS2595/MP28301 settings against datasheets before manufacturing.
Thought for 3 sec
I’ll inspect the current schematic and project docs, run design checks, then fix any schematic issues I find before summarizing what remains for layout.
Worked for 52 sec
I’m blocked because the account has no available ACUs, so I can’t continue AI layout actions right now.
Completed this session:
- Verified the schematic/ERC state: no open errors or warnings were reported.
- Set up the PCB as a 45 mm × 30 mm rounded rectangle with a standard 4-layer stackup and 0.5 mm board keepout.
- Confirmed the board area is workable, though routing may be tight around the ESP32/power section.
Remaining work:
- Place components with ESP32 antenna keepout, USB-C edge placement, compact buck/eFuse layout, and isolated SHT41 placement.
- Route the PCB.
- Run DRC and airwire checks.
- Fix any routing or layout violations before manufacturing export.
