nRF51822 Development Kit without nRFgo Starter Kit

[SergP]

Is it possible to use nRF51822 Development Kit without nRFgo Starter Kit? What I need - is to be able to connect couple of LEDs and buttons, can this be achieved without buying nRFgo Starter Kit ?

Yes, I've used the '822 and '422 development kits this way. You'll need connectors to which you can attach wires that plug into at least P2, see the PCA10004 schematic. I applied 3.3V to VTG, leaving the jumpers on K1 (2-3) and P4 (1-3, 2-4) as shipped. You should be able to wire LEDs and buttons as required, of course see the I/O DC specs and limit current accordingly.

Thanks, so, I do need to provide a power supply (if I don't use nRFGo) for the Dev Kit right? I thought (looking at the picture) that the kit is powered via the USB cable provided.
