Specifications
Brief Introduction
UHF RFID high performance desktop reader embedded with module which
designed by using Impinj INDY chip, maximum power supply is 25dBm. 15dBm
is recommended as fixed power
USB interface is available for power supply and communication, which reaches
the most simply connection
With internal 3dBi circular polarization antenna, tag reading distance is
adjustable from 0 to 1 meter.
High read rate as 200 tag/s
Two GPIO connect to LED light and buzzer, clients can easily control IO
according to the special requirement
Good writing performance, well suitable as desktop reader or identifying device
for high performance industrial application.
