I've recently found a local store that had pi0's in a starter pack for $20 and picked one up. I finally wired everything together (very stupidly) without testing all my connections out. However, I did test the NiceShopping screen (blue board) with the MicroUSB breakout, which was running off around 5.25v (Edit: It worked perfect off the 5.25v). However, when I power my gameboy and test the voltage going to my screen, it's only getting around 4.88v. Mind you my screen is actually wired into the Powerboost and not the Pi or Power Breakout board. I even tried plugging the MicroUSB charging cable to see if that would boost the power enough, but the same voltage came across.
At first I definitely thought it was the SD card, but the screen still doesn't power after I plugged the SD card directly into the Pi0. (Which I've come to notice doesn't turn on when I use the cartridge and the reader, but directly plugged in I see all the green lights on the pi0 light up.)
Note: The screen will flash very quickly about 10sec after I flip the power on like it wants to turn on. I'm currently at work writing this post and won't be able to test anything for another 4 hours. I have a variable voltage DC jack I may wire to the screen and see if the voltage, or screen connections are the issue.
Here is an image of my completed and non-working GBZ!:
Do you guys see anything I could have accidentally wired backwards? Or do you guys have any thoughts on solutions I should try?
Do you have a 6V+ power supply handy? You could also hook up 4 AA batteries in series and use that to test.
) since then.
. I am using the "octopus" USB hub, and had it wired BACKWARDS.... which was in turn wired to my power breakout backwards. So, I bought two octopus' and tried the second one (i also cut part of the first to make it smaller) and it worked perfect. My screen power, and everything works as it should.
