Here's the humble beginnings of my project starting with a PCB paper cut-out. I ordered components for power regulation slated for Thursday delivery. I will call this board "One for All".

Almost done with this thing.. Just going to double check some measurements. I have ordered all the parts as far as I know. I will be making a PCB for a front access USB and Micro SD and a back PCB with video/audio output. I was thinking about going with component to allow it to be paired with a retro tink to crank it up to 4k one day.

Awesome board, very clean. How do you plan on mounting a heatsink? Looks like a tight fit with just that little hole cut out for the CPU/GPU.

I'm going to trim some finned aluminum and the fan will go at the actual air vent.

Edit: Just ordered the board below

Welp, my N-channel mosfet works with the switch but I get no voltage out of my regulators. I think I need some help from an electrical engineer.

My diodes were backwards...... Apparently I just don't understand the full concept. I had the negative bar on the ground side, but when I checked the manufacturer's data sheets the negative was facing away from the grounds.

Edit: Got this done later in the day. The PCBs showed up in the mail.

Going to see how many wires I can connect to this board today. Had to trim it because it was blocking 2 MX vias. I'll have to modify the PCB more when I get the chance but I'm going ahead with this one for now.

Just need to do the SD card wires now.

No video output :(. Checked my data connections and those are good. I have 4.2V on my 3.3 which cannot be remotely good. This is a board with only homebrew on it and no RVloader. I have the wifi and bluetooth going so those should be fine. I hope that 4.2v didn't toast anything.

Edit: I have just now ordered a new 44.2Kohm resistor for RFB2 as well as a longer 26 pos .5 pitch ffc cable. Shipped economy, of course.
