<![CDATA[Relay on I2C port cause M5Go to restart.]]>I'm testing the relay on Port A as its listed as a digital I/O port.
When triggered the relay works fine but when it releases the M5Go restarts.
Is this just me or an issue with the relay module.

@ajb2k3 Can I know the source of your picture?

Sorry, Gimme a sec to find it. Its a common diagram of the flyback/bypass diodes connected in relay modules

It is fine on the I/O port (B) but on A it cause the trip. I am worried that this could cause premature failure of io pins.

I remembered the question you said.

Anti-back charge diode.

Is it convenient for you to give detailed information? Especially the photos
