UART Serial Port Handheld UHF RFID Reader 900mhz Close Reader Module (Near Range 50cm)

Description

Module offers a compact, reliable, easy-to-design and cost-effective EPC G2 proximity reader module solution. Output power 12dbm, receiver sensitivity -70dbm (12dbm launch test), can achieve a maximum of 50cm stable reading distance (9662 label test). Using TLL UART serial communication, low power consumption, is the desktop card reader, Internet of things teaching equipment, mobile handheld devices close proximity UHF-RFID read and write the preferred solution.

If this module can not meet the requirements of your reading distance, you can understand our home in the distance module, and long distance module. Three module sizes, pin definitions, are identical to the instruction set, allowing you to upgrade your hardware.

18dBm adjustable power UHF UHF-RFID mid-range module

25dBm adjustable power UHF UHF-RFID remote module

In addition, the module is bare board, without a test board, you need to have a certain degree of hardware development capabilities, in order to achieve for the reader, which is essential antenna:

On the reading distance is not high, the lowest cost PCB common dual ring single ring antenna link

Requires stable close-up read and write performance, with a distance of 15cm from the 25mm ceramic antenna link

Cost-effective radiation field concentration, with reading distance of 30cm 45mm ceramic antenna link

Cost-effective radiation field wide, with reading distance 40cm 65mm four-arm helical antenna link
