What antennas have you tried, I plan on looking into being able to change the NFC (TAG) message programmatically if it’s indeed possible. Maybe some smart seeed guys or gals has an answer.
I see it requires tuning with the correct caps. I’m curious to find out how thick of material (PLA or Carbon-fiber nylon) would it pass through. ANy ideas or thoughts on the subject is appreciated.
