RFID UHF integrated reading and writing module F90A1-L

F90A1-L is a UHF integrated reading and writing module based on PHYCHIPS PR9200 design. The maximum output power of the module can reach +30dBm. With a 2dBi circularly polarized ceramic antenna, the reading distance can reach 5m, and can achieve more than 200tags/s Tag recognition rate, multi-tag reading and anti-interference ability are stable.

The F90A1-L integrated read-write module has been verified by a large number of tests and long-term uninterrupted work (180 consecutive days), and its stability and reliability can fully meet the application requirements.

Introduction
Specification
Appearance

F90A1-L receiving sensitivity can reach -62dBm, which is more suitable for harsh application environments than traditional readers;
Provide a full-featured software development kit (SDK) and interface (API), easy to integrate with software;
Using an integrated radio frequency chip, the module performance is stable, and it is more suitable for harsh and demanding application environments;
Using carrier cancellation technology, the accuracy of tag reading is good and the range is wide;
Enhanced noise suppression for reliable data capture;
With high precision return signal strength (RSSI).

Product interface definition
