Saturn60: common questions

What microcontroller does the Saturn60 use?

The Saturn60 is built around the RP2350B-QFN80, from the RP2040/RP2350 family.

How big is the Saturn60 PCB?

The Saturn60 measures 285 × 94.6 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Saturn60?

305 components, from 83 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 Saturn60 design files?

From the Charading/Saturn60 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 Saturn60 design in my own project?

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

Can I test firmware for the Saturn60 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.
