D-Think_M100 module is a medium and short-range UHF Low-Power Embedded read-write module. The integrated design of ceramic dielectric antenna and read-write module completely eliminates the technical uncertainty brought to users by the need for additional antenna for ordinary UHF module. The module can work stably without any preliminary scheduling by users. Simple external interface conversion can realize USB, Bluetooth, WiFi and other connection modes. The integrated design realizes the miniaturization of modules and low cost; The RF design is optimized to achieve low power consumption and high performance of the module. Only 100MW transmission power can reach an effective distance of more than 2.5m.


•  Completely independent intellectual property design
•  Fully support electronic labels conforming to UHF EPC Gen2 (is018000-6c) protocol
•  Operating frequency - can be adjusted according to the requirements of different countries or regions
•  Output power: maximum 26dbm (adjustable)
•  Integrated module antenna, reading distance > 2m
•  Support secondary development
