RFID Breakout Board

The RFID Breakout Board is a universal RFID module for use with the development board of your choice – with examples provided for the Raspberry Pi and Arduino!

The breakout board uses an updated UART/USB 2.0 interface running at 125KHz with a compact design. It allows you to read the information stored on 125KHz RFID key fobs and tags – and one of each is provided in the pack!

Each RFID tag/key fob comes with a unique identity that cannot be copied, so it’s great for an access project. The reading distance is around 0-5 cm but this can also depend on the tag type. The board has an integrated antenna that supports this range.

The operating voltage is 4.5V-5.5V(DC) with a current consumption of 50mA. Baud rate is 9600 bps.
