125kHz RFID Tag Reader

As part of my course’s labs, we had to design a RFID reader board. This project served two purposes; it let us use the skills learned in our communications system lectures, and also gain practical experience in PCB design. This project was done in partnership with Harry Beadle. The board is designed to operate with 125kHz tags. These have been superseded by 13 MHz ISM tags for most modern applications. 125kHz is still the standard for animal chipping though.
