WII U RASPBERRY PI 3 FINISHED

[Fredl]

Hi, I'm doing this build as well and was wondering: Banjo used the Powerboost 1000 basic, which can deliver 2A at 3.7V. Would it be possible to use the Powerboost 1000C as well? The data sheet isn't really clear on the actual amps it will deliver, it just says 1000mA+...

Banjo stated the whole system draws 1.7A, so thats a big "+"...

Or alternatively, what kind of battery charging circuit can I use in combination with the 1000basic?
(All the ones I find are charger & DC-DC-step-up combined but limited to 1A...)

Thanks!

Nevermind, the 1000 basic and 1000C use different step-up chips, and the 1000C can't deliver as much current. Need to go with the 1000basic and a separate charging board!

Hello all. Hello @banjokazooie.

I just made a new diagram. Cleaner, I think.

But I'm encountering a riddle...

I followed this guide to find out how to wiring : https://www.sudomod.com/forum/viewtopic ... 956#p23956 and the author of the WiiU PCB disappeared too

I'm clearly lost. And i don't know where to wire the : Home Led 1, Home Led 2 and Batt Led.

And i don't know if my diagram is good

Big help and very big thanks

The battery led in original design was wired from powerboost basic, with 7.2V setup you need to wire a basic resistor divider. Read analog voltage from this divider with analog input on teensy and setup a digital output to led. Home leds as wired to digital output on teensy and a reguired event is set up inside teensy code.

Ok. Big thanks for this tips.

For the battery, i search good capacity "mAh". But i see different "A". It's important ? 10A, 15A, 20A ?

Max. charge current, Charge voltage, End voltage, continuous max discharge current...

Do I have to respect specific parameters?

Thanks a lot for showing this awesome project and provide all the informations!

But I have two questions:

1. Is it possible to just remove the battery / recharging setup and use the micro usb as power supply for the pi?

2. Can I remove the TEENSY and use 2 arcade USB encoder like this one: https://www.amazon.de/Quimat-Nullverz%C ... =srch&th=1
I don't know if the buttons and controller sticks work similar to an arcade setup so I just can rewire them.

Thanks a lot and I hope, that my questions are not to noobie

Any Lipo for raspberry is good enough as you will not be drawing that much current. Don't go too crazy on capacity as the charging will take forever. So i would say 6000-8000mAh is a good choice .

Yes you can use that for powering the raspberry.
You can remove the Teensy but you will loose analog joysticks as the arcade board are only digital.

@banjokazooie

How comes the screen ribbon cable comes out on top of your build?
Did you mount the screen upside down or do we have different models?

Mine is 6.5 inch AT065TN14 800*480. It is upside down as the bottom edge of the front cover is thinner.

True, it fits much nicer this way. One moe question though:
How did you rotate the screen? putting

Code: Select all

display_hdmi_rotate=2

into config.txt won't change anything, further when I try to check on the param with

Code: Select all

vcgencmd display_hdmi_rotate

it says

Code: Select all

display_hdmi_rotate is unknown

what am I missing?
