      Description

      This RFID module is designed for reading code from 125Khz card compatible read-only tags and read/write card. It will notify whenever 125Khz tag approaches, the tag serial number will be send via TX pin or Wiegand pin. Super small size design, it is widely applied in office/home security, personal identification, access control, anti-forgery, interactive toy and production control systems etc.

      Hello, how many multiple readers can i handle with an arduino uno? is it possible to use this reader (multiple readers) with a Raspberry PI? thank

      Hi Dear Customer, this reader uses the serial port. we suggest the software serial to readers, and hardware serial port for the PC display. So you can connect multiple readers. Bill

      Hello,can anyone tell me:1. Which IC is mounted on the module?2. What's the pinout of the module? I guess V is 3,3-5V, G is GND, RX and TX belong to the UART. But what about RST and S?3. How to interface with the module? I can't read anything from the UART when bringing a RFID-Tag into the range of the reader.Thanks

      I did a little reverse engineering by myself, so:1. There's no special RFID-IC on the module. It's a Microcontroller from ST: STM8S003F32. The RST-Pin is the RESET of the Microcontroller. I still don't know what the S-Pin is for..3. Now I can read from the UART. The supply voltage was too low.. My fault. But why is it reading just four numbers instead of five? I know that there are five numbers stored on my RFID-Tags.

      I noticed in the library that there is a buzzer output from the chip that is not broken out. Could you provide the datasheet so that I could look into adding that buzzer? Thank you.
