Project-Mach-1: common questions
What microcontroller does the Project-Mach-1 use?
The Project-Mach-1 is built around the ATSAMD21J18A-AU, from the Microchip SAM family.
How big is the Project-Mach-1 PCB?
The Project-Mach-1 measures 30.5 × 82.6 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Project-Mach-1?
82 components, from 49 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 Project-Mach-1 design files?
From the ImperialSpaceSociety/Project-Mach-1 repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the Project-Mach-1 design in my own project?
The repository has no license, so all rights stay with ImperialSpaceSociety. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Project-Mach-1 without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Microchip SAM firmware against it before you order a PCB.
