Can the nRF5340 DK read an NFC Tag without additional hardware?

[ralphjy]

I am just starting out with the nRF5340 and I see that it has an NFC antenna.  Can it read an external NFC tag without additional circuitry or does it require an external reader?

If an external reader is necessary, how does it interface to the nRF5340?

Thanks,

Ralph

Hi,

No it can't, it would require external hardware such as the Adafruit PN532 shield. The shield supports serial interface such as TWI and SPI.  I couldn't find any drivers for it in Zephyr atm, so you might have to port the drivers.
