nRF52840 DK v1.0.0

Connector interface

Access to the nRF52840 GPIOs is available from connectors P2, P3, P4, P5, P6, and P24.

The P1 connector provides access to ground and power on the nRF52840 DK.

Some of the signals are also available on connectors P7, P8, P9, P10, P11, and P12, which are on the bottom side of the Development Kit (DK). By mounting pin lists on the connector footprints, the nRF52840 DK 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 DK is used as a shield together with an Arduino standard motherboard, the Arduino signals are routed as shown in the figure below.
