SkripsieProject: common questions
What microcontroller does the SkripsieProject use?
The SkripsieProject is built around the STM32G031K8TX, from the STM32 family.
How big is the SkripsieProject PCB?
The SkripsieProject measures 149.2 × 185.3 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the SkripsieProject?
232 components, from 83 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 SkripsieProject design files?
From the scout-cc/SkripsieProject 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 SkripsieProject design in my own project?
The repository has no license, so all rights stay with scout-cc. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the SkripsieProject 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.
