Not really a solution. 2A charging current - 1,7A current draw = 300mA for battery charging. It would take around 20 hours when playing to fully charge a 6000mAh battery :lol:
I found somewhere that tp4056 should be used only for one cell, so I'm trying to figure out how to connect two of them to each battery.
And i was thinking about using setup similar to this: http://budgetlightforum.com/node/34765 or this: https://www.youtube.com/watch?v=KoHtxZG7leQ

also where should I connect powerboost? to battery connectors in tp4056?

The red board is battery protection and the blue one is adafruit push button switch ( at the end not used a I went for software controlled on/off switch ) and black one is the other end of sd card extension cable.
here's the updated image, you can add it on the first page if you like

The batteries are all charged separately. But connected must be in the gamepad in row. How do you solve that?

are you sure? the voltage should remain stable and capacity should be doubled, so I thought that batteries in gamepad should be connected in parallel. can banjokazooie confirm the battery setup?

-snip-
1. Basic math. Current required to power rpi3+lcd+accessories is more than 1000C can deliver. 1000 BASIC = 2A, 1000C=1A.
2. There is mic audio input on this sound card.
3. Sourcing parts used by nintendo is not an easy task without part number. I removed them and soldered wires directly to pcb board. I see no reason to used them unless you want to make a custom pcb.
1. Thanks.
2. The dac would receive sound from the raspberry pi via a connection from USB. It outputs the sound to the headphones. The jack itself seems to be labeled J2 and the pins are labeled on the back as R7, c12, c13, and R8 with one pin unlabeled. I am guessing that the mic would connect to one of these four pins and then the ground for the mic would connect to the other while the output to the speakers go to the other pins but I don't know which would be which. Any help would be appreciated as the mic is important to me and this is my first project.
3. Yeah. I figured it'd be hard to find. I also thought that the parts may even be proprietary one offs ordered by Nintendo. I'll use my backup plan and replace both the male and female connectors to one I can easily source. I would love to learn to make my own custom PCBs though!

Thanks for the help. I really appreciate your sharing your knowledge with me and the rest of this community. I've already learned a lot.
