Bill of Materials
This is a list of components you need to build the OpenTendo NES. You will need some components from the original NES and have to order more modern components.
From the OEM NES
| Reference | Qty | Part | Description |
|---|---|---|---|
| U5 | 1 | RP2C02 | PPU |
| U6 | 1 | RP2A03 | CPU |
| P2 | 1 | Connector | 48 pin expansion port |
| P6 | 1 | Connector | 5 pin connector for the power/reset breakout board |
Alternatives
| Reference | Qty | Part | Description |
|---|---|---|---|
| P2 | 2 | PPPC241LFBN-RC[1] | 24 Pins Header Connector 0.100" (2.54mm) Through Hole |
Note
[1] If you don't want to use the OEM expansion port, you can replace it with a header pin connector or not put anything at all. OpenTendo should still work without the expansion port.
What to buy
We recommend using Octopart's BOM tool and import the BOM.csv. This tool makes ordering from multiple Octopart's authorized distributors (Digikey, Mouser, etc.) easier.
