AMR PCB Design
Worked for 1 min 13 sec
The complete schematic is built: 136 components, 109 named nets, dual high-current regulators, four DRV8874 motor channels, Pi/ESP32 interfaces, sensors, servo bus, and protected power distribution. Independent ERC, passive-component, and availability checks report no open errors or warnings.
Open items before PCB layout
- Confirm the exact DOIT ESP32 DevKit V1 30-pin orientation.
- Verify encoder outputs are 3.3 V-compatible.
- Confirm servo connector and status-beacon current ratings.
- Six simultaneous servo stalls remain outside the 7.4 V regulator envelope.
Project files
The next phase is PCB stackup, board dimensions, thermal placement, and high-current routing. Confirm these open items and I’ll proceed with layout.
Thought for 4 sec
I’ll review the updated layout constraints and confirmations, then incorporate them into the PCB setup and placement plan.
Thought for 1 min 5 sec
I reviewed the confirmations and existing PCB: it is currently 160 × 100 mm, 4-layer, with all 136 components present, but placement has several congested/unroutable regions. No layout mutations were made because the account ran out of available ACUs.
Remaining work:
- Apply confirmed ESP32 pinout and encoder-power changes.
- Add four corner M3 mounting holes with 5 mm keepouts.
- Re-place components into thermal/functional zones.
- Configure power-plane and ≥2 mm motor-routing rules.
- Route copper and complete DRC remediation.
Thought for 2 sec
I couldn’t analyze or modify the PCB because no ACUs are currently available, so AI layout features cannot run.
The board remains 160 × 100 mm, 4-layer, with 136 components present. Based on the last verified state, both component placement and trace routing are needed, followed by DRC cleanup. No new changes were applied.
