This was a summer project of mine this year. I had always wanted to make a business card out of a PCB I ultimately settled on two designs:
- A card with just RFID capabilities linking to my Github.
- A card with a temperature sensor displaying to a LED thermometer.
I decided to design the cards in Altium (Free for students) and I provided the files in the design_files folder for both designs. The design for the temperature sensor is untested but, the simple design works great. Some advice for putting files on to the RFID chip.
- Download STM's NFC Tap app.
- Create a CC file and write E1 40 00 00 to the first block of memory.
- Next, go to the memory editor and to the second block write: 03 00 FE 00. This formats the chip.
- Next, use the non-manual writer to write any data to the chip.
- Should work now on iOS.
