I can’t modify the project right now because there are no available ACUs, so AI execution features are unavailable.
Current state: no design changes have been made in this session. The requested migration is to replace the existing ESP32 controller with an ESP32-C3 SuperMini module and replace the current motor driver circuitry with A4988 stepper driver modules.
Remaining work once ACUs are available:
- Identify the existing ESP32 DevKit and TB6612FNG motor-driver connections.
- Select or create suitable ESP32-C3 SuperMini and A4988 module components.
- Re-map GPIOs for STEP/DIR/ENABLE, limit switches, sensors, I2C OLED, RC input, and any remaining interfaces.
- Update power architecture for ESP32-C3 logic and A4988 VMOT/motor supply requirements.
- Rewire schematic, then run ERC/design review.
- Update PCB placement/routing after schematic migration.
