These kicad project files are automagically generated from the original Altium files using: https://github.com/thesourcerer8/altium2kicad/

They are provided for people who want to make their own board variants, and thus it is up to the person making a derivative to verify the board for correctness as these have never been tested.

Sparky2: common questions

What microcontroller does the Sparky2 use?

The Sparky2 is built around the 497-11767, from the STM32 family.

How big is the Sparky2 PCB?

The Sparky2 measures 34.9 × 35.3 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Sparky2?

69 components, from 28 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 Sparky2 design files?

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

Can I use the Sparky2 design in my own project?

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

Can I test firmware for the Sparky2 without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
