Gpio pin to voltage source

Can I connect gpio pin to 3v directly?

Hi @apereira1014,

If you are using it as an input pin then yes you can directly connect it to 3V. If set as output, the device might restart, but will not cause an issue to the system.

Do let me know in case you need further assistance.

Thanks for the reply. I’ll try and let you know
