# Famicom USB + Composite Power Board Replacement

In this repository you'll find the schematic and PCB layout for the Famicom powerboard replacement as shown in [this episode of Hakk's Lab](https://www.youtube.com/watch?v=6UGa3aDpMOE). You'll need [Design Spark PCB](https://www.rs-online.com/designspark/pcb-download-and-installation) to open the project files. Exported gerber files can be found in the `gerber/` directory.

## Parts List

Below are the parts used in this layout with suggestions for potential improvements or changes.

- 1 [3 RCA female AV cocentric socket](http://a.co/d/7VnQlFh)

- 1 USB connector of your choice. For this layout, I used a [female USB type-B connector](http://a.co/d/i00tf1e)

- 3 150 ohm resistor. Alternatively, two of these could be replaced with a 300 ohm resistor. I didn't have any 300s, so I seriesed up a couple 150s to get the correct resistance

- 1 110 ohm resistor

- 1 PNP transistor

- 1 1uF electrolytic capacitor

- 1 220uF electrolytic capacitor

- 1 red LED. Honestly, it could be any color, but be sure you use the correct resistor for whatever you actually use. I think red is appropriate in this case because 80s technology and it matches the colors of the Famicom.
