FDX-A FDX-B RFID Animal Tag Reader Module UART Interface FDXB FDXA

Card type: 134.2KHz animal Tag(FDX-A/B)

Card reading distance: 4CM (2*12 glass tube), 3CM (1.5*8.5 glass tube), test results are for reference only

Working voltage: 5V

Working current: about 25mA

Output interface: UART (9600, N, 8, 1)

Data format: 16Hex ASCII code

Coil size: 60mm*75mm

Wiring diagram:

Notice:Antenna frequency is 125khz, compatible with the 134.2 FDX protocol em4305 tag

When you test the product with an oscilloscope, you will find that the frequency of this device is 125khz. If your chip is not em4305-FDX please do not buy.   Replacing 134.2khz with 125khz to read FDX-B is a low-cost solution.
