nRF52 as NFC reader

Is it possible to use the NFC functionality in the nRF52 series chip to read NFC tags?

  • Hi Cristian, the board looks nice and clean, nice job! I'm wondering if I2C provides enough bandwidth in case you need to do some roundtrips between BLE MCU and PN532, solutions I know usually use faster SPI at 4 or 8 MHz. Also using nRF52840 might be useful because of larger buffer sizes SPIM (TWIM seems to be stuck at 8 bits = 255B which might be limiting in some cases, but I haven't studied PN532 wired protocols in detail). But as far as I know there is no "open hardware BLE equipped NFC reader" so it looks useful! I hope you get funded with your project. Cheers Jan
