UHF RFID Unit (JRD-4035) photo

Unit RFID-UHF is an ultra-high frequency (UHF) embedded wireless RF read/write module. It adopts the JRD-4035 module solution with a built-in ceramic antenna, completely eliminating the technical uncertainty caused by the need for an additional antenna in ordinary UHF modules. The optimized RF design achieves low power consumption and high performance, reaching an effective range of over 1.5M with just 100mW transmission power. Using a serial communication interface along with a built-in… (M5Stack U107)
