SNSP-CPU-01
About the SNSP-CPU-01 PCB
SNSP-CPU-01 is an open source PCB design by stonedDiscord, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 215.8 × 159 mm, with 276 components from 88 distinct parts.
Other key parts include the CPU, PPU1, PPU2, MS62256CL-10FC and WRAM. By type, the board carries 98 resistors, 94 capacitors, 17 ICs, 16 transistors, 12 connectors and 7 diodes.
From the project
Super Nintendo Entertainment System PAL schematic and board layout
The design tries to be a 1:1 recreation of the original SNSP-CPU-01 Rev5 and SNSP-CPU-1CHIP boards.
If you decide to get it assembled I suggest only getting the bottom side with all the SMD components done and doing the top yourself. The bottom only has jellybean capacitors, resistors, diodes, transistors so it's not going to be very expensive.
For the top you will have to salvage the Nintendo components. The video RAM is still being made by S@Tech (HM62256). The audio RAM can probably also be easily replaced, I haven't looked into this yet. Feel free to open an issue about it.
