Compact ESP32 Motor Driver PCB
Worked for 5 mins 3 sec
Placement is done cleanly. I’m routing the board now so the motor, battery, and ESP32 header pads are physically connected, then I’ll check for remaining issues.

Built the compact ESP32 mini-drone motor driver project: added and wired 4× AO3400 MOSFET channels, 4× SS14 flyback diodes, 10kΩ pulldowns, 100Ω gate resistors, 100nF capacitors, JST-PH battery input, ESP32 external wire header, and 4 motor solder pad pairs. I also renamed the project to Compact ESP32 Drone Motor Driver, set it as a 30×30 mm 2-layer PCB, placed all parts compactly, and ran auto-routing.
Open items:
- Auto-routing completed, but the last check still reported 6 remaining airwire issues around motor low-side connections; these need manual cleanup or another routing pass.
- Routing produced warnings that some motor traces are wider than small SOT-23/diode pads, so those paths should be reviewed carefully.
- AI features are now unavailable because there are no available ACUs, so I can’t continue editing right now.
Suggested next steps:
- When ACUs are available, ask me to “fix the remaining airwires and verify DRC.”
- Review the ESP32 header pin labels before soldering; the header footprint uses generic pin names, but I mapped them as GND, VBAT, PWM1–PWM4.
- After DRC is clean, export Gerbers for PCB manufacturing.
