Hello,
I have multiple grove NFCs which work perfectly fine sometimes but some other times, it might not detect the antennas or does not detect the tags. Some other time, it would randomly start working again. Sometimes turning on/off the system does the job but still, the issue is very very persistent and I’m not able to find a stable solution. I used them with Arduino UNO and Arduino Micro. Also, using a multiplexer to have multiple antennas at one go. Tried using them separately as well, but this issue is common between all scenarios and I’m not able to build a totally stable system. Please help me if possible.
Hi there
maybe you should use DC jack to power board which is great solution
Hi, thank you for that.
So I want to understand why this is the solution. USB power is not enough and I should try to use jack?
Hi There
Yes , Grove NFC need enough power supply
