https://devzone.nordicsemi.com/f/nordic-q-a/68393/signals-and-power-lines-involved-in-program-debug-nrf52810Hello, We are currently developing a project based on nRF52810. We are testing some examples to learn more about this chip. Now we would need to know which signals and power lines are necesary to program/debug our own board.

In addition to SWDIO and SWDCLK you should route VCC, GND and the RESET signal to the J-link header.&nbsp;</p> <p>You can download the schematic of the PCA10040 on the product website <a href="https://www.nordicsemi.com/-/media/Software-and-other-downloads/Dev-Kits/nRF52-DK/nRF52DKFW110.zip">here</a>.</p> <p>Also, see my answer on <a href="https://devzone.nordicsemi.com/f/nordic-q-a/67958/serial-wire-flash-writing/278453#278453">this thread </a>for more information regarding SWD.</p> <p>regards</p> <p>Jared&nbsp;</p><div style="clear:both;"></div>
