JRD-4035 module is a mid-range and short-range UHF low-power embedded read-write module. The ceramic dielectric antenna is integrated with the read-write module, which completely eliminates the technology brought to the user by the need for an additional antenna for the ordinary UHF module. Uncertainty, without the need for any preliminary scheduling by the user, the module can work stably, which is true PLUG & PLAY. Simple external interface conversion can realize USB, Bluetooth, WIFI and other connection methods. The integrated design realizes the miniaturization and low cost of the module; the optimized RF design realizes the low power consumption and high performance of the module, and the transmission distance of the only 100MW can reach an effective distance of more than 1.5M.
