Saturn: common questions
What microcontroller does the Saturn use?
The Saturn is built around the SPARTAN6LXXXX-CSG324, from the FPGA family.
How big is the Saturn PCB?
The Saturn measures 62.8 × 57.5 mm and is 1.6 mm thick.
How many components are on the Saturn?
151 components, from 40 distinct parts. The full bill of materials is listed on this page.
Where can I download the Saturn design files?
From the numato/samplecode repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Saturn design in my own project?
The repository has no license, so all rights stay with numato. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Saturn 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.
