The KiCad project lives in the Duet3D/Duet3-Expansion-3HC repository on GitHub; these links point at the commit this page was built from.
Duet3-Expansion-3HC: common questions
What microcontroller does the Duet3-Expansion-3HC use?
The Duet3-Expansion-3HC is built around the SAME51N19, from the Microchip SAM family.
How big is the Duet3-Expansion-3HC PCB?
The Duet3-Expansion-3HC measures 100 × 100 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Duet3-Expansion-3HC?
365 components, from 108 distinct parts. The full bill of materials is listed on this page.
Where can I download the Duet3-Expansion-3HC design files?
From the Duet3D/Duet3-Expansion-3HC repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Duet3-Expansion-3HC 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-Expansion-3HC 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.
