UHF Module

UHF MODULE --- A high performance UHF module with 8 SMA antenna ports

  • RF output power up to 33dbm and reading distance up to 15m
  • Fast reading speed up to 300 tags/second
  • Free demo software and SDK


  • High economic benefit: improve the use value of RIFD equipment and reduce the number of RFID equipment used by the project.
  • Easy to integrate and apply: The core radio frequency part of RFID is packaged in a centralized manner, and it can be used only by power processing and connection development.
  • High stability performance: It has excellent radio frequency performance and can also do a variety of self-test optimization.
  • Fast tag response speed: while maintaining a high reading rate, it can realize fast reading and writing processing of electronic tags, which is very suitable for dense environments.
  • High-speed eight-antenna polling: each antenna can achieve a minimum polling time of 25ms, and the port residence time can be automatically allocated according to the actual distribution of tags.
  • Meet the national standard: meet the national standard GB/T29768-2013.
  • Support intensive reading, multi-tag identification, tag data filtering, and perceivable model strength.
