<p>As the title says, I would like to power a companion computer (Raspberry Pi 3B in my case) using the PM07 Power Distribution Module: <a href="https://docs.px4.io/master/en/power_module/holybro_pm07_pixhawk4_power_module.html" rel="nofollow noreferrer">Power Module</a></p>
<p>The Raspberry Pi should be powered via USB cable.

What would be the best/safest way to go about this, without the need for another BEC if that is possible?</p>

@Magnuss I got another 5V BEC and powered the PI over the pin header directly. The USB cable/connector caused significant voltage drops for me, leading to an unreliable power supply of the PI (still working but got frequent undervoltage warnings).
