Is DL533N XL compatible with an Arduino? #
The DL533N Series of devices do not have physically extracted UART pins. The only communication interface available is USB.
Therefore, for Arduino implementation, a USB-to-serial converter is required.
If Libnfc implementation is not specifically required for your project, you might consider using our µFR XL NFC Reader since it supports UART.
µFR XL is based on our API and Communication protocol, and it comes with an Arduino library.
