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

I had a similiar problem. The cause was not enough current being supplied over USB (<=2.9V on DK, measured at VTG).

Try the following: Short circuit VDD over VTG to device.

This enabled me to programm all devices without any trouble. From my experience you need to have at least 2.95V to programm the NRF.

Best

My voltmeter says I'm outputting 2.86volts to my custom PCB through the nRF 52 DK and the DK picks it up fine.
