Questions
How big is the Ivy Basic PCB?
It measures 42.2 × 42.2 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Ivy Basic use?
48 parts, built around the ESP32-S3-MINI-1-N8, SSP9451, TMC2209-LA and 1N5819WS. 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 Ivy Basic KiCad files?
From the CasualCodersProjects/Ivy repository on GitHub, at the commit this page was made from: the board is Ivy-Basic/Hardware/Ivy-Basic/Ivy-Basic.kicad_pcb and its schematic Ivy-Basic/Hardware/Ivy-Basic/Ivy-Basic.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ivy Basic design in my own project?
Its repository states no licence, so its author keeps all rights: ask CasualCodersProjects before reusing the design.
