  • Hi,

    This adapter works with the J-Link programmers. 

    Since the pitch and pin-out of the pins on the DK is different it will not work if you try to use it for programming one DK with another. See this schematic for the pin-out on the DK. Pins 3, 5 and 9 are connected to GND and pin 7 is not connected.

    If you want to use the nRF52840 DK to program the nRF52832 DK (or your custom board) you will have to make an adapter between the 10-pin connector (black end, without the pogo pins) and the DK. I have not seen this kind of adapter sold anywhere.
