PWM Signal Voltage MOD

The newest batch of Pixhawk baseboard V2 now supports switchable PWM signal voltage (3.3V or 5V). The modification requires the user to open the casing of the Pixhawk flight controller and be familiar with soldering.

Any damages caused during the modification are not covered by warranty

To switch the PWM signal voltage, bridge the 3v3 or 5v soldering pads on the PCB by applying solder on the pads. Make sure the unused pads are cleaned and not shorted.

Pixhawk baseboard V2-A and V2-B have slightly different PCB designs. Follow the red square in the diagram below to locate the PWM voltage select soldering pad.
