The Raspberry Pi Pico RFID Expansion boasts an advanced RFID Reader at the frequency of 125KHz with a compact design, including a programmable 0.91” OLED Display and UART/I2C interface compatible with Raspberry Pi Pico. Read the information stored on an RFID key fob and tags as part of your project! Every RFID tag/key fob comes with a unique identity that cannot be copied. There are control jumpers that allow the user to control and change the OLED, RFID reader and buzzer pins. Note: Pico Board Not Included. Your Pico will need to have male headers soldered to it (with the pins pointing downwards) to attach to our add-on boards (or grab a pre-soldered Pico here).
