1 open source board using the SAMD21G
Real designs built with the SAMD21G, from public GitHub projects: a quick way to see how others power, decouple and connect it. Each board comes with its KiCad files, full parts list and a render — and you can simulate its firmware on HardLabs.

Microcontrollers on boards using the SAMD21G
What boards using the SAMD21G are built for
SAMD21G: common questions
Where can I find a SAMD21G reference design?
Each of the 1 boards on this page is a real design using the SAMD21G. Open one to see how it is wired up, with the full BOM, a render of the layout and links to its KiCad files.
Which microcontrollers do boards using the SAMD21G use?
Most are built on Microchip SAM (1).
How big is a typical board using the SAMD21G?
The median is 57 × 97 mm, and 100% are two-layer designs.
What is the most popular open source board using the SAMD21G?
By GitHub stars, OpenFence by plyalex, with 28 stars.
Can I simulate one of these boards using the SAMD21G before building it?
Yes. HardLabs turns a board's netlist and BOM into a working simulation, so you can boot and test firmware against it with no hardware on your desk.
