Atsamd21: common questions

What microcontroller does the Atsamd21 use?

The Atsamd21 is built around the ATMEGA16M1, from the AVR/Arduino family.

How big is the Atsamd21 PCB?

The Atsamd21 measures 88.9 × 88.9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Atsamd21?

39 components, from 24 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 Atsamd21 design files?

From the Olin-Rocketry/boards repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Atsamd21 design in my own project?

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

Can I test firmware for the Atsamd21 without the hardware?

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