NES:NESRevival-PSU
Originally created by Merlin Shaw and currently maintained by Alchem and Guardians_projects, the NESRevival power supply board project is a complete redesign of the NES AV and power board, which reduces potential electromagnetic interference (EMI) and noise. The original NES power module is very noisy and poorly laid out, with power traces crossing each other and a convoluted ground path. EMI was not as much of a concern in 1985, but the noise generated by the original power module can impact picture and sound quality.
Project Goals
- 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 power module design for each use case (i.e. one specifically for AV output, one with a provision for a 9-pin mini-DIN connector, etc.)
- Keep units in stock, allowing for repairs to exist in the present day
- Maintain updated installation instructions and bill of materials (BOMs)
About the Project
There have been many improvements made to this project over time, including the addition of some safety features to allow extra tolerance for faults. The project is open, and design improvements are welcomed.
The project is open sourced using the MIT license. It can be edited, changed and, sold at your own discretion. However, the author requests a link back to the original GitHub if this helps you with your own project. You can find ways to manufacture and source the boards over on the project GitHub if interested.
