Hi,
I have recently purchased a Wemos D1 to play around with, and although I realize it is a very powerful chip, I've decided to communicate my sensors with it via an Arduino UNO (UART).. Now, my question is do I still need to power my UNO with a 3.3v to allow it to communicate safely with Wemos? Or can I just power the UNO with 5v and Wemos will do the rest for me?
Any help would be great
