I created the ESP32-S3 carrier schematic with USB-C 5 V input, protected 5 V/3.3 V rails, ESP32-S3-WROOM-1, BNO085, SHT40 temperature/humidity sensor, GPS UART header, motor-driver carrier header, boot/reset buttons, status LED, and supporting passives; ERC/passive checks were clean, while layout/routing and generic passive MPN selection remain unfinished because no ACUs are currently available.
Open items:
- PCB placement/routing not started; DRC airwires are expected.
- Exact GPS module, motor driver carrier, motor voltage, and stall current still need confirmation.
- Generic resistor/capacitor MPNs need to be assigned before manufacturing.
- Motor current-sense protection/scaling should be finalized after choosing the driver carrier.
Project files created:
Suggested next steps once ACUs are available:
- Confirm the exact GPS module and brushed DC motor driver carrier.
- Finalize VMOTOR voltage/current limits and current-sense scaling.
- Assign production MPNs for generic passives.
- Proceed to PCB placement with ESP32 antenna keepout and motor-current separation.
