The µFR Nano Online wireless NFC reader is a cross-platform NFC Reader Writer that uses an ESP32 system-on-chip microcontroller in conjunction with Digital Logic’s proprietary API and communication protocol.
On all MCU platform-based FR Series hardware, proprietary interoperable firmware from Digital Logic is running. Through the fast FTDI chip’s direct access, the reader and host can communicate.
The device’s primary communication protocol is a proprietary one developed by Digital Logic.
Many intricate built-in functions in the FR Series firmware can be invoked using libraries that are described in the API docs.
