Need help wiring

[JLund1n]

Hello everyone! I’m fairly new to this and don’t want to damage any of the parts with incorrect wiring. Can someone please give me a little guidance on what exactly should go where? Thx!

well... you should probably check some videos and forum posts where people have detailed their builds first. there's at least a dozen ways to do it.

given what you have there, you would have been better off also getting the pro gpio assist board from pocketadventures, then it's essentially a matter of lining it up in the case and connecting "a" to "a", "r" to "r", "start" to "start", etc. once you have the pi soldered in.

you don't need that adafruit powerboost - the pro power assist has boost+charge built in.

if you are going to use that amp, you probably also want a low-pass filter to clean it up (pocketadventures also has one of those), but if you got the gpio assist pro, that has usb audio built in, which sounds much better. otherwise, the principal is the same as wermy did in his original video.

if you don't do the gpio assist, then you will need to solve the button mapping yourself (not too hard, but you'll need to understand the gpio inputs somewhat to hook it to the correct ones). that is like, for instance, wiring the "A" on the button board to gpio pin "5", etc. there are tons of resources on how to do that (for instance, search for "gpio controls" or "retrogame" from adafruit).

for video, those pins line up with that video board, once you've put the pi in the correct spot (on the front half of the shell). the hardest part is getting the flat cable to sit in its connector correctly, which is what you want to use a little bit of masking tape to do, to make the cable a little thicker and snug-fit.


conceptually, as-is, this is a lot like my second game boy color build, so the notes in there might be able to help you out: viewtopic.php?f=43&t=8233

I’ve gotten to this point and I am a little unsure as to how I’m going to wire the switch in. Everything else I understand just a little confused about this part.

you do not want to use that powerboost. the red board has that functionality on it already.

i don't know what you mean by "wire the switch" since it is also integrated into the red board. the two wires you run to the pi's gpio are to trigger the software shutdown with a script, but unless you set that up, the switch should just work as a typical on/off to cut its power.

i think you need to spend more time understanding what each of your components are meant for.

So to not use the power boost how would I connect it to the power assist?

the battery is connected to the b +/- and then the 5v rail is your output that you run to your different components, at their VIN (voltage in), like your pi, audio amp, etc

Ohhhhh. I’m so sry I didn’t even notice the power assist had that on there. Thanks for the help;)
