125KHz RFID Module with ST232(RS232 IC)


SM125-M1-232 is a 28 pin DIP module  including all neccessary components for a 125 KHz RFID Reader except for only the antenna. 


  • Using SoC as a single chip including microcontroller, analog circuit and antenna driver results in World's lowest count and smallest RFID reader.
  • Firmware upgrade-able for custom specific applications
  • Requires only antenna and power supply to function.
  • Automatically demodulates and decodes RF signal and make the actual tag data ready
  • Supports Atmel/Temic T55xx transponders and EM4100/02.(Unique)
  • Supports Manchester RF/32 and Manchester RF/64 modulations
  • 5V or 3.3V operation ( 3.3V option requires different firmware upgrade)
  • UART Interface up to 115200bps - I2C Interface up to 400KHz. SM125-M1-232 comes with RS232 driver(optional)
  • Control-able General Purpose Outputs and Inputs 
  • Supports flexible and programmable Wiegand 26 bit output format 

 
SM125-M1-232 is the same module with SM125-M1 and additionally it includes ST232 IC (RS232 driver chip)

It can be controlled over UART-RS232 /I2C or can read tag data automatically without requiring any external controller.

Module performs all required analog and digital signal processes and make the tag data ready to be sent over UART/ I2C/ Wiegand and can output signal to trigger Buzzer/LED/Relay circuit.

It is integrated with bootloader and can be upgraded over UART-RS232. Customization is available.
