Sci board: common questions
What microcontroller does the Sci board use?
The Sci board is built around the STM32L496VGT6, from the STM32 family.
How big is the Sci board?
The Sci board measures 80 × 80 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Sci board?
197 components, from 51 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 Sci board design files?
From the MatthiasGeorgImhof/Hardware_CSAT 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 Sci board design in my own project?
It is published under CC-BY-NC-4.0, which limits how it may be reused; read the license before building on it.
Can I test firmware for the Sci board without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
