RFID active read-write module 2.45G active read-write module active PCie interface module rfid module

RFID active read-write module 2.45G active read-write module active PCie interface module rfid module

The PCIE interface RFID read-write module works in the ISM frequency band 2.45GHz RFID read-write module. The module has the characteristics of high recognition rate, flexible expansion, high sensitivity, stable data transmission, and high reliability. The transmission distance of the module can reach 0-150 meters. It is mainly used in system integration applications such as portable data collectors, industrial data transmission, sensor data acquisition, and industrial control.

Work in the ISM band 2.45GHz, data transmission is free. Provide TTL RS-232 interface and multi-channel IO control interface, module connection control is more convenient. The module integrates PA and signal conditioning circuit, the input/output power can be controlled by software, and the transmission distance can be controlled. The module supports low power consumption technology, and the working power of the module can be turned on and off through the external control port; API development kits, application instructions and sample codes are provided to facilitate rapid integration and application.
