I’m looking for recommendations for antennas that work and are tuned for the XIAO nRF52840. I see there is a wiki article for how to use the NFC pins and some software example. Has anyone found any off the shelf antennas that work for NFC with this board?
I was looking for something similiar, I have came across this one from seeed itself, I think you can cut the connector and solder it to the XIAO. I didn’t bought it or tried it myself (yet)
I do not believe that the antenna NFC Antenna will work
- It does not have the correct connector and cutting this cable will not give you nice wires to solder onto the pad.
- There are no tuning capacitors attached. So I believe this antenna only works for the boards it is advertised fro.
However I did not try it out myself. If anyone is successful with this antenna, please let me know.
You might find my comprehensive post on this thread useful. I explained how to get the NFC working.
