UHF Module

UHF MODULE --- A four-way SMA antenna interface module and supports up to 33dBm of RF output.

  • 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


  • Strong compatibility: The module supports a variety of development languages and development environments and provides a feature-rich standardized SDK development kit and interface.
  • Excellent heat dissipation performance: With a full-alloy aluminum exterior and large heat dissipation contact surface design, the module has good heat dissipation performance and does not require an external heat sink.
  • Excellent reading performance: The module has excellent analog RF circuitry, and optimized baseband signal processing algorithm and anti-collision algorithm.
  • Excellent stability: The module can detect the operation status of CPU and antenna connection status by itself and has excellent anti-electromagnetic interference performance.
  • Wide range of applications: The module can not only be quickly integrated into fixed and all-in-one readers, but also can be applied for terminal projects.
  • Fully compatible with mainstream air interface: Support ISO 18000-6C/EPC C1G2, ISO 18000-6B, GJB 7377.1-2011, GB/T 29768-2013, (optional).
  • Support dense reading, multi-tag recognition, tag data filtering, and can sense the strength of the model.
