Description

The Reyax RYRR20I_DE is a multiprotocol RFID transceiver module designed for 13.56MHz HF band operation. It integrates the antenna, RF front-end, and protocol stack into a single compact unit, simplifying integration for proximity and vicinity identification systems. The module communicates via a straightforward UART serial interface at 115200 baud, making it compatible with a wide range of host microcontrollers and single-board computers.

Its firmware supports a comprehensive command set for reading and writing operations across multiple standards, including ISO14443A/B, ISO15693, FeliCa, and ISO18092 (NFC). With an operational range of approximately 4cm and an RF output power of 20dBm, it is suited for secure, short-range data exchange. The module’s wide temperature range and low-power design enable reliable performance in industrial, commercial, and embedded IoT applications.

Key Features

  • Fully integrated 13.56MHz RFID antenna and transceiver circuit.
  • Supports multiple RFID/NFC protocols: ISO14443A/B, ISO15693, FeliCa, and ISO18092.
  • Standalone operation mode for automatic card detection and reading without host intervention.
  • UART serial interface with configurable baud rates up to 115200bps for easy MCU integration.
  • Built-in RF field detector for presence sensing and power management.
  • Customizable firmware command set for advanced control and data manipulation.
  • Robust design with an operating temperature range of -40°C to +85°C.
  • Compact, ready-to-use module requiring minimal external components.

Frequently Asked Questions

How do I connect the RYRR20I_DE module to an Arduino or ESP32?

Connect the module's TX pin to the microcontroller's RX pin and its RX pin to the MCU's TX pin. Provide a stable 5V power supply to the VCC pin and connect GND. Initialize the serial port in your Arduino IDE or ESP-IDF sketch at 115200 baud to send and receive the module's command set for reading RFID tags.

What is the difference between standalone and host-controlled modes?

In standalone mode, the module automatically powers up, initializes the RF field, and begins reading any presented RFID card, outputting the UID via UART without any host commands. In host-controlled mode, you must send specific configuration and read/write commands via the UART interface to manage the RFID transaction process and data handling manually.

Can this module write data to ISO15693 tags?

Yes, the RYRR20I_DE module supports writing data to specific memory blocks on ISO15693-compliant RFID tags. You must use the appropriate write command from the module's firmware command set, sent via the UART interface, specifying the block address and the data payload you wish to store on the tag's memory.

What is the maximum baud rate supported by the UART interface?

The module's default factory baud rate is 115200 bits per second. While the datasheet specifies this rate, some Reyax modules may support other standard baud rates (e.g., 9600, 19200, 38400, 57600) through configuration commands. Always verify supported baud rates in the official product datasheet before changing from the default setting.
