# No power or resets

Check battery polarity and connector seating.
Check for supply-to-ground shorts.
Inspect solder bridges and damaged parts.
Verify module supply voltage under load.
Check whether motor activity causes controller or sensor power instability.

# One motor does not behave correctly

Confirm the logical motor number and GPIO mapping.
Inspect the motor, wiring, MOSFET/driver path, and solder joints.
Compare the failing channel with a known-good channel.
Keep propellers removed while diagnosing.
