The design has realized a miniature and embeddable UHF RFID reader ＆ writer module with the RF transceiver chip PR9000 as a core chip. This module can work under the frequency range from 860 MHz to 960 MHz adjusting by the software and compatibly support the EPC global Gen2 and ISO18000-6C standards, with small size and low power consumption. The area size of this module is 20mm×25mm, while its power consumption is 120mA@3.3V. When working with the 2.5dBi antenna, it can read and write within the distance 200 mm. To be embedded into other PCB boards easily, the module supplies an UART interface and pads to external modules, which is of great commercial value.
