Description
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.
Card type: 134.2KHz animal Tag(FDX-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
Module size: 20mm*30mm
Coil size: 60mm*75mm
Wiring diagram:
Notice:Antenna frequency is 125khz, compatible with the 134.2 FDX protocol em4305 tag
