The Compact UHF RFID Reader Module U1-PT-02 is a miniature embedded reader designed for smart locks, access control terminals, compact identification devices, anti-counterfeit systems and other OEM applications requiring controlled short-range UHF RFID identification. Measuring only 25 × 25 × 10 mm and weighing approximately 15 g, the module integrates a built-in PCB UHF antenna and communicates with the host controller through a TTL interface. It operates from a 3.3-5V DC supply, making it suitable for space-constrained embedded products.
The module supports EPC Class 1 Gen 2 / ISO 18000-6C and GB/T 29768-2013, with RF output power from 3-20 dBm. Typical reading distance is approximately 0-5 cm depending on tag performance and the installation environment. Anti-collision processing supports multi-tag identification with a peak inventory speed of up to 30 tags per second, a 100-tag buffer at 96-bit EPC, RSSI reporting and receiver sensitivity down to -67 dBm. Chip temperature monitoring and SM7 security algorithm support are also provided for embedded applications requiring additional system monitoring and security functions.
TTL communication operates at a default 115200 bps and can be configured according to system requirements. SDK resources include dynamic libraries, example code, demo software, user manuals and operating documentation for host-system integration and secondary development. Firmware adaptation, security interface expansion and project-specific embedded integration can be discussed according to application requirements.
