Access to the nRF52832 GPIOs is available from connectors P2, P3, P4, P5, and P6. The P1 connector provides access to ground and power on the nRF52 DK.
Figure 1. nRF52 DK connectors
The signals are also available on connectors P7, P8, P9, P10, P11, and P12, which are on the bottom side of the DK. By mounting pin lists on the connector footprints, the nRF52 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 P13–P17.
Note: Some pins have default
settings.
- P0.00 and P0.01 are by default used for the 32 kHz crystal and are not available on the connectors. For more information, see Section 32.768 kHz crystal.
- P0.05, P0.06, P0.07, and P0.08 are by default used by the UART connected to the interface MCU. For more information, see Section Virtual COM port.
- P0.09 and P0.10 are by default used by NFC1 and NFC2. For more information, see Section NFC antenna interface.
- P0.13–P0.20 are by default connected to the buttons and LEDs. For more information, see Section Buttons and LEDs.
When the nRF52 DK is used as a shield together with an Arduino standard motherboard, the Arduino signals are routed as shown in Arduino signals routing on the nRF52 DK.
