Samd: common questions
What microcontroller does the Samd use?
The Samd is built around the ATSAMD21E17A-A, from the Microchip SAM family.
How big is the Samd PCB?
The Samd measures 75 × 50 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Samd?
21 components, from 10 distinct parts. The full bill of materials is listed on this page.
Where can I download the Samd design files?
From the NB6RULES/Nadec-Biju-Fabacademy-Files repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Samd design in my own project?
The repository has no license, so all rights stay with NB6RULES. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Samd 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.
