This project is an electronic board placed under a Märklin C-Track to detect the presence of a train. The board is connected via a second bus on I2C.
RFID tags are placed under the train. The board detects the presence of the train by reading the RFID tags.
The standard NFC used is ISO/IEC 14443 Type A. The RFID tags are MIFARE Classic 1K.
- Find a connector small enough to fit under the track
- Do a schematic review
- Finish routing the board
- Add a resistive measurement on the track to detect the presence of a train
- Study feasibility of differential I2C-bus with PCA9515
- Verify antenna matching what L and impedance?
- Update antenna matching component values
