Power Module

Power module is the best way to provide power for PIXHAWK or standalone PX4FMU v1.7 autopilot. It has voltage and current sensors that allows autopilot to estimate remaining battery charge precisely. It comes with every Pixhawk as default kit.

Always connect the power module. Not using the power module will put your system at the mercy of the ESC BEC and is therefore not supported as normal operation procedure.

Where to Buy


  • Max input voltage: 18V
  • Max current sensing: 90A (as provided by the manufacturer, effective maximum rating is lower due to thermal limits. About 30-60 amps continuous and 90A for a few seconds burst should be fine though)
  • Voltage and current measurement configured for 5V ADC
  • Switching regulator outputs 5.3V and 2.25A max
  • 6-pos DF13 cable plugs directly to PIXHAWK 'POWER' connector
