WII U RASPBERRY PI 3 FINISHED

[phdirnou]

Which kind of LED colors did you solder on the Home board and in which order?
Because the original Wii U homeboard has only two diferent LEDs. A red one to show you the battery capacity, which is either blinking or steady or off, and a blue one for the "Home" button. If I read the pi_power project on github right, than we have either some RGB LEDs or a green one and a red one.

And another question.
Will it work with the Pololu Step down converter/pushbutton power switch?
Because as in the pi_power project described, he uses an Adafruit PowerBoost 1000 Charger.
So many questions...
Sorry for that, I'm a noob in electronics and thank you for your answers

What is this component in red?

ON/OFF Push button circuit

Do you have a link to where I could buy this part? Was this even used in the final build? Figuring out the power on/off and batter monitoring is the last thing I need to complete my build but I'm not sure how this all got wired together in your build.

It is a simple circuit you can make yourself

Yeah after some research I was beginning to make that conclusion

So that is only the on/off push button circuit from here?: https://github.com/craic/pi_power

What is the big black component? I don't see anything in that schematic that would look like that

It's not serving any purpose for the analog/digital converter that is listed as the 2nd hardware subsystem in the article? Do you even need that converter or are the LED's just wired directly to the charging board and powerboost?

I'm still pretty confused about how all of the bottom buttons are working and how the battery status functions work. Can you confirm that the below pic from a previous post has the soldering points correctly identified on the bottom circuit? Or if not how you determined the solder points? What color LED's do you use for low battery, charging, charged, power on, etc.?

Nevermind I think I found the answers to my questions in the last post. All of the LEDs are working according to that pic I posted.

Still not sure what the black component I asked about was. At this point I'm leaning on just putting a mini slide switch in between the charging board and powerboost and just using the emulation station shutdown option from the main menu to power down and the switch to power back on.

Other than the aesthetics of using a slide switch vs the power button and the convenience of the software enabled shutdown - are there any drawbacks to doing this?

If your board charging have already "overshoot/over discharge protection" do you really need "BATTERY PROTECTION CIRCUIT 8A"?

Battery protection board is a must for non protected lipo battery packs. The charging circuit have no protection build in. The big black part is a capacitor used for Rpi version 3

Thank you for answer.

I looked at the links, a best option could be the https://www.usinainfo.com.br/arduino-or ... -2595.html

Ok I have two more questions. Everything is working except my LEDs. I have two issues I'm still having:

1. I decided to use a slide switch for the power on/off instead of the method you linked to. Not sure if that is related to my problem but currently the powerboost low battery LED is always on (both the LED I have wired to it and the onboard LED). Below is a pic of how I have it wired. Does anything stand out to you as an issue?

2. I'm not able to pinpoint where to solder the LEDs onto this charging circuit to turn on the charging (orange) and full charge (blue) LEDs on the wii. Would anyone know?
