Sd2snes: common questions
What microcontroller does the Sd2snes use?
The Sd2snes is built around the XC3S400-PQ208, from the FPGA family.
How big is the Sd2snes PCB?
The Sd2snes measures 101.5 × 83 mm and is 1.6002 mm thick.
How many components are on the Sd2snes?
147 components, from 48 distinct parts. The full bill of materials is listed on this page.
Where can I download the Sd2snes design files?
From the magnotrans/sd2snes repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Sd2snes design in my own project?
Yes, under the terms of its GPL-2.0 license, which magnotrans chose for the repository.
Can I test firmware for the Sd2snes without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug FPGA firmware against it before you order a PCB.
