Programming an external custom board with nrf9161dk

Programming a board with custom connections (nordicsemi.com)

nRF9160DK has the SW9 to switch between 3V and 1.8V, while nRF9161DK use 1.8V by default.

Is it possible to power your custom board with nRF9161DK as the guidance suggests?

Best regards,

Charlie

Thanks for your answer. Just to be sure about my wire, I've only connected VTG, CLK, DIO and GND. On VTG I have 3.3v and SW9 is set to 3v maybe the issue is here...

Hi Simon,

1) In the Figure 1 of your linked page, SW9 is the switch.

2) You should generate a custom board for your board if you want to do functional test, but you can program any nrf9160 firmware with J-Link. The logs show you have problem with programming, this is properly due to IO voltage level mismatch.

Best regards,

Charlie
