Blixten: common questions
What microcontroller does the Blixten use?
The Blixten is built around the STM32F302K8U6, from the STM32 family.
How big is the Blixten PCB?
The Blixten measures 35 × 20 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Blixten?
60 components, from 29 distinct parts. The full bill of materials is listed on this page.
Where can I download the Blixten design files?
From the jonasblixt/blixten repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Blixten design in my own project?
The repository has no license, so all rights stay with jonasblixt. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Blixten 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.
