PN532

Post by nfctore »

It's possible to connect two PN532 NFC / RFID with only one Arduino (one rev.3 or Yun)? Thank you.

Probably not.

The PN532 uses I2C to communicate with the Arduino, and the device address is fixed in hardware. You'd need two I2C buses, with separate control objects and buffers for each, and that would probably push the limits of the Arduino's SRAM.
