GT2650 5v rail to power Pi Zero

[Gary]

I'm looking to add Repetier Server capabilities to my Geeetech I3 Pro B.

Does anyone know if there is a 5v rail I can pull from the GT2650 board so that a Raspberry Pi Zero can be powered?

I'm about to start going around with a multimeter on the board's connectors including the ribbon cable for the screen but thought best to ask here first.

Thanks.

I noticed there is a "5V" slot around the mainchip and you also can use the "VDD" pin on the motor driver A4988?
