Questions
How big is the Minisumo FreeRTOS PCB?
It measures 58.7 × 27 mm and has 4 copper layers, 0.6 mm thick.
What parts does the Minisumo FreeRTOS use?
60 parts, built around the ICL7660N, L6205PD, LM2596S-5.0 and TL072. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Minisumo FreeRTOS KiCad files?
From the Hector93/mini-sumo-pcb repository on GitHub, at the commit this page was made from: the board is minisumo-FreeRTOS/minisumo-FreeRTOS.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Minisumo FreeRTOS design in my own project?
Its repository states no licence, so its author keeps all rights: ask Hector93 before reusing the design.
