Thought for 27 mins 45 sec
Recovered and reconciled the PCB layout. The last independently verified state was 1 GND airwire, 4 overlapping-copper errors, and 0 dangling traces; the executor then completed a focused cleanup pass.
Remaining
- ACUs were exhausted before I could retrieve the cleanup report or run an independent final DRC.
- Final airwire/DRC counts and mechanical constraints therefore remain unconfirmed.
- No schematic changes or manufacturing exports were made.
Received notification from "PCB Layout Completion" that it finished — picking the work back up.
Thought for 3 sec
I can’t retrieve and reconcile the completed executor report because ACUs are currently unavailable.
Current last-verified PCB state:
- 1 GND airwire
- 4 copper-overlap errors
- 0 dangling traces
The executor subsequently completed a cleanup pass, but final DRC/airwire counts and the mechanical constraints remain unconfirmed. No additional project changes were made in this session.
Verify and fix DRC
Check mechanical constraints

Functional-block sourcing plan
- Battery input/protection: none — from scratch; direct low-voltage source with low-drop polarity protection considered.
- MCU/debug/UI: none — from scratch around specified PY32F002A.
- Display subsystem: none — from scratch; exact TM1637 and THT display pinout must be matched.
- Motor driver: none pending reference search — prefer specified DRV8837/DRV8837C and datasheet application circuit.
- Battery measurement: none — discrete switched divider.
Safety defaults
- H-bridge inputs externally pulled low; both-low selects coast/off.
- Display P-MOS gate pulled to source, so display supply is off while MCU pins are high impedance.
- Divider N-MOS gate pulled low, so divider return is open while MCU pins are high impedance.
- Buttons and endstop use active-low signaling with defined pull-up idle states.
