UniSNES: common questions

What microcontroller does the UniSNES use?

The UniSNES is built around the RP2040, from the RP2040/RP2350 family.

How big is the UniSNES PCB?

The UniSNES measures 125.5 × 45.6 mm, has 4 copper layers and is 1.5 mm thick.

How many components are on the UniSNES?

61 components, from 25 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the UniSNES design files?

From the HandHeldLegend/UniSNES repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the UniSNES design in my own project?

The repository has no license, so all rights stay with HandHeldLegend. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the UniSNES without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
