My device runs at 3.3v, what Nordic dk should I use to program it?

[koeg]

I read somewhere that the nrf52840 dk can change it's vdd via software, so it can be set to 3.3v, thus it can program a nrf5340 device with it's internal j-link debugger. Could this be done with the nrf5340 dk? Or that only runs at 3v

Hi,

 

I read somewhere that the nrf52840 dk can change it's vdd via software,

Newer kits, which has a board controller, can adjust certain parameters in nRF Connect for Desktop -> Board Configurator.

It is usually 3V on the nRF52840-DK:

https://docs.nordicsemi.com/bundle/ug_nrf52840_dk/page/UG/dk/hw_debug_out.html

 

so it can be set to 3.3v, thus it can program a nrf5340 device with it's internal j-link debugger. Could this be done with the nrf5340 dk? Or that only runs at 3v

nRF54L-series DK's can adjust the VDD, and the debug out accepts a voltage range as defined here:

https://docs.nordicsemi.com/bundle/ug_nrf54l15_dk/page/UG/nRF54L15_DK/program_debug/debug_out_ext_board.html

 

Kind regards,

Håkon
