RHD622 Embedded UHF RFID Reader Module

RHD622 Embedded UHF RFID Reader Module

Overview

The RHD622 is a long-range high-performance passive UHF RFID reader module operating in the 840~960MHz band. It simultaneously supports ISO18000-6C, GB/T 29768 and GJB/T 7377 tag protocols. Featuring low current draw, high sensitivity (-70dBm), and RF output up to 21dBm with a wide 5~12V DC input range. Ultra-compact at 36x56x4mm and only 20g, equipped with TTL UART and 4 GPIOs for easy embedded integration.

Key Features
