I am using a 6V power source for a gas sensor I'm using. Then I'm using the on board 5V to power an LCD I am using. So, I am using two power sources.
My question is if I wanted to use a 9V battery, would that be able to power both components without needing to use a USB cable? I want to make my gas sensor more mobile and portable. I don't know much about power sources, and whether or not something is getting enough power.
Thanks!
