SMARTRFTRXEBK: Connecting an External MCU - Powering the TRXEB using USB Power


When connecting an external MCU board to the TRXEB, is it possible to power up the TRXEB using USB power from my laptop (i.e. short circuit the USB and LCL pins on head P17) as a third option to power the board?

The reason I ask is that I cannot power the external MCU board from the TRXEB and powering from an external power source (bench supply) is not practical (I need to be able to move around while testing).
