BareSam development board: common questions
What microcontroller does the BareSam development board use?
The BareSam development board is built around the ATSAMD51J19, from the Microchip SAM family.
How big is the BareSam development board?
The BareSam development board measures 86 × 54.1 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the BareSam development board?
38 components, from 24 distinct parts. The full bill of materials is listed on this page.
Where can I download the BareSam development board design files?
From the synthkore/drivepackhw repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the BareSam development board design in my own project?
The repository has no license, so all rights stay with synthkore. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the BareSam development board 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.
