Internal 5V powersupply Devo (6s)

I want to build-in an Oplink tranceiver and power it from de Devo remote. So when I turn on the Devo, it will power the Oplink. And when I shut down the devo, it stops powering the oplink.

I know I read something here in the forum somewere about internal powersupply, but wasn't able to find it.

Is it even possible to power the Oplink from the Devo (6S)? It needs 5V.
