Pico RFID Expansion

Raspberry Pi Pico RFID Expansion is the latest technology in the range of SB Component products boasting an advanced RFID Reader at the frequency of 125KHz with a compact design that has a programmable 0.91” OLED Display and, an updated UART/I2C interface running, that is compatible with Raspberry Pi Pico. It helps the user to read the information of the ID stored on the RFID key fob and tags. Every RFID tag/key fob comes with a unique identity that cannot get copied. There are control jumpers that allow the user to control the OLED, RFID reader, and buzzer pins, other than the default pins.

Features

  • UART/I2C Communication Interface.
  • Supports 125kHz Key Fob/ Tags.
  • Programmable buzzer.
  • I2C/ UART Buzzer selection Jumper.
  • Onboard Programmable 0.91” OLED Display. ​
  • Compatible with Raspberry Pi Pico. ​

  • Specifications

  • Operating Voltage - 5V
  • DRFID Tag Frequency - 125 kHz
  • Communication Interface - UART/I2C
  • Default Baud rate - 9600 bps
  • Pinout

    PICO RFID Board PICO Pins
    OLED SDA GP11
    OLED SCL GP10

    Installation

    MicroPython

  • Stack Raspberry Pi Pico on female header of Pico RFID Expansion Board.
  • Connect USB cable on Raspberry Pi Pico USB port.
  • Make sure all jumpers are connected.
  • Open Thonny IDE and Choose interpreter as MicroPython (Raspberry Pi pico).
