Questions
How big is the Didactic main PCB PCB?
It measures 124 × 100 mm and has 4 copper layers, 1.57 mm thick.
What parts does the Didactic main PCB use?
257 parts, built around the STM32G431CBT6, 10067847-001RLF, NXB0108PWJ and USBLC6-2SC6. 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 Didactic main PCB KiCad files?
From the Edu4Chip/Didactic_PCB repository on GitHub, at the commit this page was made from: the board is PCBs/Didactic_main_PCB/Didactic_main_PCB.kicad_pcb and its schematic PCBs/Didactic_main_PCB/Didactic_main_PCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Didactic main PCB design in my own project?
Its repository states no licence, so its author keeps all rights: ask Edu4Chip before reusing the design.
