Navio2 - UART power supply

On Navio2, what is maximum current draw from UART port? I want to be sure not to pull too much power from the port…

Is there a datasheet available somewhere for NAVIO2 that has this spec?

Cheers!

No more than 1A which is a limit for pins on DF13 connector.
Apart from that the power on UART connector is the same as for RPi+Navio, so it depends on your power source and consumption of other components (RPi, Navio, USB WiFi etc.).
