https://devzone.nordicsemi.com/f/nordic-q-a/121427/nrf52840-1-8v-programmerHello everyone, We are developing products with nrf52840 and our default supply voltage is 1.8V. Is it possible to program a custom 1.8V board with nRF52840DK? We are thinking to use segger jlink edu mini but the target voltage is 3.3V, so we areen-USTelligent Community 13Wed, 14 May 2025 10:34:20 GMThttps://devzone.nordicsemi.com/thread/535300?ContentTypeID=1Wed, 14 May 2025 10:34:20 GMT137ad170-7792-4731-bb38-c0d22fbe4515:5e093e20-5e0e-4a6b-91d1-6cf701c597dbSimonr<p>Hi</p> <p>The nRF52840 DK only supports programming 3V targets, but the nRF54L15 DK<a href="https://docs.nordicsemi.com/bundle/ug_nrf54l15_dk/page/UG/nRF54L15_DK/program_debug/debug_out_ext_board.html"> supports programming and debugging external</a> nRF51, 52, 53 and 54 series SOCs within 1.8V-3.6V. So that might be a cheaper option to program 1.8V targets.&nbsp;</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>
