Some of the signals are also available on connectors P7, P8, P9, P10, P11, and P12, which are on the bottom side of the board. By mounting pin lists on the connector footprints, the nRF52840 Preview DK board can be used as a shield for Arduino motherboards1 or other boards that follow the Arduino standard.

For easy access to GPIO, power, and ground, the signals can also be found on the through-hole connectors P13P17.


Some pins have default settings:

When the nRF52840 Preview DK board is used as a shield together with an Arduino standard motherboard, the Arduino signals are routed as shown in the figure below.
