The 4-Port UHF RFID Reader Module U8 is a high-performance embedded reader designed for warehouse automation, production line tracking, vehicle access, smart cabinets, asset management, RFID portals and other fixed RFID applications requiring multiple external antennas. The module provides four 50 Ω SMA antenna ports and supports EPC Class 1 Gen 2 / ISO 18000-6C and GB/T 29768-2013 for reliable multi-tag identification.
RF output power is software adjustable from 6-32 dBm. Under suitable tag, antenna and environmental conditions, read distance can reach up to approximately 10 m, while write distance is typically up to approximately 10 cm. The reader supports anti-collision processing, RSSI reporting, a peak inventory speed of up to 500 tags per second, a 700-tag buffer at 96-bit EPC and receiver sensitivity down to -70 dBm. RF output accuracy is specified at 1 dB with output flatness of ±0.5 dB.
The module operates from a 5V DC supply and uses USB virtual serial as the standard host interface, with RS232, HID and TCP/IP configurations available according to project requirements. SDK resources include dynamic libraries, example code, demo software, user manuals and development documentation for host-system integration and secondary development. Communication interfaces, RF parameters, antenna configuration, firmware and project-specific integration can also be adapted for OEM applications.
