Wiring Diagram: mintyPi controller PCB

Post by djbriane » Sat Jun 24, 2017 12:04 pm

Here is the final wiring diagram based on Wermy's guide for anyone who wants a full picture of what connects to what. One thing to note is the Raspberry Pi actually sits ABOVE the controller PCB, but for some reason Fritzing doesn't allow me order the components in that way (if anyone knows why, please PM me!).

Thanks again for doing this. :) The only things I'd tweak are powering the USB sound card from the button PCB (connected to the same power input pads). The way you have it will work, but you need less wires to reach the button PCB pads. I also found that the resistors weren't really necessary. :)

Updated the diagram to match your guide - let me know if anything looks incorrect!

I can't seem to upload a pic from my phone, but anyways, is there a reason my pi won't boot/power up? The screen is receiving power through the pcb but not the pi and I'm not sure why, I've got everything soldered as depicted above and it even works when I powered the board during the testing stage of wermys guide but after putting the rest together(twice now) my screen is the only thing that gets power(Not white, it's a black screen but can see the back light come on)

Upload pictures to a website like postimg.org and then post the links here to the images. Also this has what to do with the wiring diagram? You need to stick to your thread or make a new one with your problems instead of posting this everywhere. It's likely a bridge or a broken solder connection from the Pi to the PCB, are you testing continuity like Wermy did in the video to each test pad?

Don't contact me about obtaining my board files (as you will not get them). Don't contact me about any of my boards if they are sold out, they will be restocked as soon as I can get them.


Don't support thieves like ckliang who copied my AIO to resell and is now cloning the mintyPi, support the original creators and not the thieves!

I think the wiring for the R button is wrong. You have the wire going from the button to the R pad but the leg That you are connected to is also sharing the common ground with L.

This is true.

R pad wire should be connected to one of those two bottom pins on that switch.

Good catch! Fixed it and attached an updated image/fritzing file.

Thanks!

Hah, I happened to load the page after you fixed it but just before you replied, @djbriane. I was sitting here looking at the diagram going "that looks right to me... What are they talking about?"

Nice catch guys. :)

While most are obvious, what does Pad1 connect to?
