Yobo schematics

Hello and thanks for reading!

Anyone have a schematic for the Yobo system? I saw a hand-written verison of one tied into a SNES on here, but I'm looking for a simpler breakdown of the three boards and their pinouts.

My two main questions: Will it run on less than 200 mA, and where's the best place on the board to draw LCD power from?

Any help is appreciated. Thanks in advance.

ok here is the thing (correct me if I am wrong fellow members)

The screen and the yobo require a similar voltage so all you have to do is just run the power in parallel to power the screen

The yobo, I believe, doesn't have a convient voltage out so just pull the 5 volts for the LEDs (if you want them) off the screen

Also, this isn't as complicated as initially thought, the schematic for the yobo isn't required, just take the voltage in and the ground and attach it to a battery.

The attach the ground for the screen and attach its voltage in to the battery's cathode (+) end

Place a switche where needed and then you have a mobile yobo, hard wire the controller and you can design and build a case that fits you, and that is really all there is to it!

Hope that helped!

PS the wiki designed and not utilized is a whole lot of help

You only need the middle board. Follow the traces from the controller, audio, video, and power. None of the components of the other boards are needed. (not even the 7805. Pull the 5v off your screen)

Thanks for the input. Hope to start soldering this weekend.

I posted one before. Here:

I did this in a few minutes when I was bored.

Here's one I made to help remember. Hope it helps.

Please note that there is a 1uF, 50v electrolytic cap between Audio + and -.

You can skip the cap, it sounds fine

i need a little help with this and i no this thread is a little old but i hope someone can still help me. I was wondering where the audio + and - is on joevennix's diagram and how to hook up the batteries to it. Thanks

audio - can be any ground at all and just give it 5 volts to the red and hook the - to any ground

ok got it thanks but now where do i hook up the + and - for the battery Thanks

Put the +5v into the white pin on the right. Then you have to solder the red and black pins on the left to turn it on - by doing this, you are jumping the on/off switch. Sorry the colors aren't really the standard conventional ones (red for ground... what was I thinking)

so if i hooked a 5v battery up that way would i need a regulator like would it be fine with out one if not how would i hook that up?

joevennix - Can you please send a clearer picture with clear writings under? I really need that.

just solder the middle of the audio to the spot that says audio and the middle of the video to the spot that says video and solder the outside wire/ring to the second to the last spot that is the ground and to run it off 5v's just solder the + to the last spot and the - to the ground for the controller part look at gunnex's picture its easier to follow and and u dont have to amp the audio on joevennix's pic
