Completely Redesigning the NES Power Module to Reduce Noise and EMI
1/30/2025
I would like to thank the retro community for the love and support I have received over the years.
At this time, I will no longer be offering these NES Boards on eBay or other channels.
It's been a great couple of years but I must move on to other things in life.
All of the Boards should have their Kicad files and Gerbers available on this Github.
It's not too bad ordering 5 of them pre-assembled from JLCPCB and then just sell the other 4 to get a free board. :)
I will not be able to provide support as well on these but I absolutely recommend the NES Help section on Dubesinhower Discord.

There are a lot of amazing folks on that Discord Channel and in our community.
Thank you for letting me be a part of it.

The RGBNES "Companion" Power Board v3.1b has passed it's prototype phase and I am ordering a production run.
We are getting close to being able to release the gerber files for this design. I just want to verify with the new order.

I have a small sample of the new RGB "Companion" 3.0 Boards that are available
I will also update the classic design with the new features of the RGB Board and offer that one as well.
The original NES Power Module from the 80's is very noisy. The Power Traces cross eachother and the ground home path is messy. EMI was not a worry in 1985 but noise can impact picture and sound quality

- Full Ground Plane that is uninterrupted and is free of traces and components.
- Power Traces that do not cross and have the GND plane below for a good return power signal.
- Have a specific NES Power Module for each use case (not try and pile everything into one board)
For the few that own the NES HDMI Board, this module will provide very easy solder points without the need of the LDO.
Below is an example of the Orignal Power Module. Notice how the power traces keep crossing eachother and other components. Folks really didn't consider EMI a lot back then and opted to just cover the entire board in a metal shroud.
