Wiring Diagram: mintyPi controller PCB

[HoolyHoo]

While most are obvious, what does Pad1 connect to?

3.3V rail

I believe thats more of a convention thing to indicate which pad is #1 (don't think it connects to anything on the controller PCB).

It's there just for numbering and also to help align it knowing that square GPIO would be going there. That was a remnant of the previous versions before all the fancy silk screen was added.

I noticed that in the Fritzing PCB diagram, the A button appears to be connected to pin 2, but on the printed board from this screenshot



it looks like A is connected to pin 1. Am I looking at something wrong? I'm relatively new to wiring my own electronics and don't want to loose the magic smoke in all my new toys.

Pin 1 is the square GPIO on the bottom right.

Pin 1 is the square GPIO on the bottom right.

But the A button connects to Pin 2, correct?

The GPIO pins start from right to left the way the Pi is positioned in the photo above, and yes the A is the bottom GPIO on the left.

Derp. Thank you!

Edit: I've figured it all out using the posts in moosepr's signature, and via this topic: http://www.sudomod.com/forum/viewtopic.php?f=22&t=2312 Only thing I'm noticing is that the framerate is dropping pretty hard on my ili9431. I'm not sure if it's the nature of the screen, fbcp, or if I don't quite have the settings right. Tweaking with it now, any advice is appreciated!

I'm sorry if this is an obvious question, I wasn't able to get any custom PCBs but I wanted to build a few of these to give away as groomsman gifts at my wedding.

I'm going based off of the Fritzing diagrams and all the photos and videos I can find on the forums. So far, I believe I've gotten all the pinouts figured out as to which button connects to which GPIO pin. The part where I get lost is when it's time to hook up the battery and charger. Does the VCC from the custom board plug directly to the 5v and 3.3v GPIO pins 4 and 17? I also wasn't sure if I needed to step the power up through something like the powerboost to get the 3.7v battery up to 5v, or if I can wire the battery directly to the GPIO pins.

I had to build this out of parts I could find, so I ended up with one of these chargers:


The battery will obviously plug into B+ and B-, but I'm not sure what to wire the OUT+ and OUT- to. I would think OUT- should go to the Pi's ground GPIO pin, but I have no idea...
