I am currently using the HolyBro PM06 PDB to power my Pixracer R15 via the power cable that came with the PDB.
I have used this setup previously on another build and it worked fine however i have just finished assembling a Robocat 270 reusing this hardware and when the Pixracer is plugged in via USB both it and the receiver get power.
However when using a Lipo neither the Pixracer nor the receiver get power despite the ESCs initialising.
I have continuity checked all the wires that connect the PDB and flight controller and couldn’t find any breaks and connectors on both ends were intact, so was unsure where to check next.
Any help would be greatly appreciated.
