Powering a peripheral device

Hi All,

I am new to PX4 hardware development. I am working on a remote sensing device to be mounted on a vehicle. I am trying figure out what is the power capability of the PX4, how many amps can I draw from the 5V pin on one of the telemetry connectors? I have been going through the documentation but I am still a little bit confused and haven’t been able to answer this simple question. Also, the schematic for the FMU does not provide any information on this particular item, which increases my confusion even more.

Any help will be greatly appreciated.
