A low-frequency RFID reader designed and built to explore the fundamentals of LF RFID communication systems at 134.2 kHz.
This project uses the EM4095 RFID analog front-end with an ESP32 for signal processing and data handling. A custom PCB with an integrated coil antenna was designed specifically for this implementation.
The system operates at 134.2 kHz and detects compatible LF RFID tags through magnetic field coupling. The EM4095 handles signal amplification and demodulation, while the ESP32 processes the received data.
The project was developed as a practical hardware learning experience covering:
hardware/ -> PCB layout and schematic files
software/ -> ESP32 firmware
