nrf51822 Minew's Module is not recognized by NRF51DK

[fercholas]

Hi guys

I am trying to program a nrf51822 module but it is not recognized by the development kit.

These are the pins that I am using:

I can not see the module with NRFGo on Windows or on linux with Jlink console.

Any idea?

Thanks in advance!

Hi,

previous answers are correct that you need to short VCC to VTG.

Additionally you need a proper GND connection to your circuit, as GND_DETECT (pin 8 on P20) is an "input" that triggers use of external module (might be an oversimplification). I suggest you short one GND from connector P1 to your module, and short another GND to GND_DETECT.

Best regards,

Pin 8 needs to go to Module's GND AND a GND on the DK. So you need to run two wires off Pin 8 - one to Module and one to many of the GND pins on the DK.
