Question #
Is DL533N XL is compatible with an Arduino setup?
Answer #
DL533N Series of devices do not have physically extracted UART pins, so the only available communication option is the USB. Therefore, for implementation on Arduino, you need to use a USB to serial converter.
If you are not bound to Libnfc, I suggest using our µFR XL NFC Reader which supports UART.
µFR XL is based on our API and Communication protocol, and we also provide an Arduino library for it.
