General Description:
The module is supports up to 33dBm of RF output. Provide function-rich standardized SDK development kit
and interface, the user can be quickly integrated in a short time. At the same time, the read/write module is
independently molded and fully die-cast in aluminum, with exquisite appearance and excellent heat
dissipation performance, and can be widely used in challenging application environments such as
warehousing, logistics, garment, and production line management.
Features:
• 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.
