Powering the nRF51822 Development Kit

[Andre Lochner]

I bought the nRF511822 development Kit, not realising that it needs the nRFgo motherboard to supply power to it.So i have to make do with what I have. I am trying to power the board, I connected 3V3 to pin 1 on P2 and GND to pin 5 on P2. I can program and verify with the J-Link and the nRFgo software. When i run the blinky demo nothing happens and I can see no current draw on my supply. Is there any other pin i need to connect to 3V3 or GND ? It almost look to me like the device is stuck in reset ?

Any help will be appreciated !:)

Have you had a look at this?

I would expect that connecting pin 1 on P2 should be sufficient, but as you can see from the schematics, it will depend on which position the jumper on K1 is in.

K2 should be the header in the corner of the board, which can be used for current measuring. The header with the jumper should be K1.

I'm also a little surprised that you don't see any current draw, and I therefore suspect that there is something wrong with your connections, and would recommend you to try a different way of connecting.

If you still have trouble, I'd be happy if you could edit your question and upload a picture or two of your setup, to make it easier to understand.
