Smd challenge: common questions
What microcontroller does the Smd challenge use?
The Smd challenge is built around the ATSAMD21E15B-M, from the Microchip SAM family.
How big is the Smd challenge PCB?
The Smd challenge measures 41.3 × 31.8 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Smd challenge?
26 components, from 21 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 Smd challenge design files?
From the mokomull/smd-challenge repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the Smd challenge design in my own project?
The repository has no license, so all rights stay with mokomull. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Smd challenge 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.
