The KiCad project lives in the Duet3D/Duet3-Mainboard-6HC repository on GitHub; these links point at the commit this page was built from.
Duet3 MB: common questions
What microcontroller does the Duet3 MB use?
The Duet3 MB is built around the ATSAME70Q20B-AN, from the Microchip SAM family.
How big is the Duet3 MB PCB?
The Duet3 MB measures 134 × 140 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Duet3 MB?
642 components, from 165 distinct parts. The full bill of materials is listed on this page.
Where can I download the Duet3 MB design files?
From the Duet3D/Duet3-Mainboard-6HC repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Duet3 MB design in my own project?
It is published under Custom license, which limits how it may be reused; read the license before building on it.
Can I test firmware for the Duet3 MB 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.
