Brief Introduction
➢ UHF RFID high performance desktop reader embedded with modulewhich 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 0 dBi circular polarization antenna, tag reading distance is adjustable from 0 to 1 meter.
➢ High read rate up to 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.
