Yep. Just connect the 5V from GPIO if the powerboost is giving you headaches. Have in mind that connecting to the Pi you will also see the low power rainbow rectangle if it draws too much power (undervolt). I did it because of that because my display (current) is really really hot (so It probably draws too much power and looses it on heat).dirtybeagles wrote:Question on this. Do I have to do anything special is I connect the 5v and GND from the VGA to the pi0? I am having some strange issues with the VGA connected to the powerboost with flickering on the screen. I am thinking it may have something to do with my amp (still waiting on the adafruit one, because I think my current amp is using to much amperage).Cannikin wrote:Nope, any 5V connection on the control board is the same 5V so you only need to hook up one.
I actually did end up coming OUT of the 5V GPIO on the Pi and it works great!
I assume you just take 5v and GND and solder those wires to the pi0? Thats it? I do not have to run another GND wire from the PI0 to the powerboost?
Plus, you only need one ground so you can choose if it will go through the composite side or directly from the GPIO. So that way (if it's on the video cable) you can example have an external composite also (if you don't want or can't have an HDMI out) and have the signal on a simple switch. (for connecting to an older TV which doesn't have HDMI).
