Reyax RYRR20I_DE 13.56MHz UART RFID Antenna Module

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.
