SST80: common questions

What microcontroller does the SST80 use?

The SST80 is built around the RP2040, from the RP2040/RP2350 family.

How big is the SST80 PCB?

The SST80 measures 344.7 × 124.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the SST80?

152 components, from 20 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 SST80 design files?

From the dededecline/SST80 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 SST80 design in my own project?

Yes, under the terms of its GPL-3.0 license, which dededecline chose for the repository.

Can I test firmware for the SST80 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.
