Access to the nRF5340 GPIOs is available from connectors P2, P3, P4, P5, P6, and P24.
The P1 connector provides access to ground and power on the nRF7002 DK.
Some of the signals are also available on connectors P7, P8, P9, P10, P11, and P12, which are on the back of the Development Kit (DK). By mounting pin lists on the connector footprints, the nRF7002 DK can be used as a shield for 3.3 V Arduino motherboards 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.
Some pins have default settings:
- P0.00 and P0.01 are used for the 32.768 kHz crystal and are not available on the connectors. See 32.768 kHz crystal for more information.
- P0.19, P0.20, P0.21, and P0.22 are used by the UART connected to the interface MCU. See Virtual COM ports for more information.
- P0.02 and P0.03 are by default used by NFC1 and NFC2. See NFC antenna interface for more information.
- P1.08–P1.09 are by default connected to the buttons and P1.06 - P1.07 are connected to the LEDs. See Buttons and LEDs for more information.
- P0.13–P0.18 are by default connected to nRF7002. See Solder bridge configuration for more information.
When the nRF7002 DK is used as a shield together with an Arduino standard motherboard, the Arduino signals are routed as shown in the following figure.
