Sern: common questions
What microcontroller does the Sern use?
The Sern is built around the RaspberryPi3, from the Raspberry Pi family.
How big is the Sern PCB?
The Sern measures 100 × 100 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Sern?
67 components, from 21 distinct parts. The full bill of materials is listed on this page.
Where can I download the Sern design files?
From the Heppokoyuki/sern repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Sern design in my own project?
The repository has no license, so all rights stay with Heppokoyuki. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Sern without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Raspberry Pi firmware against it before you order a PCB.
