The nRF7002 DK supports a Near Field Communication (NFC) tag.
NFC-A listen mode operation is supported on the nRF5340 System on Chip (SoC). The NFC antenna input is available on connector J5 on the nRF7002 DK.
NFC uses the W1 (NFC1) and AA1 (NFC2) pins to connect the antenna. These pins are shared with GPIOs (P0.02 and P0.03), and the PROTECT field in the NFCPINS register in UICR defines the usage of these pins and their protection level against abnormal voltages. The content of the NFCPINS register is reloaded at every reset.
Pins W1 and AA1 are by default configured to use the NFC antenna, but if they are needed as normal GPIOs, R43 and R46 must be NC and R42 and R45 must be shorted by 0R.
