5V input header on boad?

On the my pocketerm board is a 2 pin header marked 5V. Is this for 5V regulated power, and if I provide power there I can leave the 2.5mm 8V external power unconnected?

thanks,
Jeff

I looked at the schematic (rtfm!) and it sure looks like the pocketerm can be powered via the 5V header (J4, I think though not labeled on board).

Also, how much current does the external 8V power need to supply?

If it is a trustworthy source, yes you can. It was designed to accept being powered from another device or to power another deivce, so both ways work. Your switch will not function in this mode.

If I read that last post right, that 5V header can be used to power an external device, if the pocketterm itself is being powered with ~8V at the normal power input. Is that correct? If so, what kind of draw can one expect to be able to pull at 5v from that header? I'm curious if it could power a pi zero... thanks!
