Questions
How big is the Orange loop PCB?
It measures 24.3 × 181.8 mm and has 2 copper layers, 0.18 mm thick.
What parts does the Orange loop use?
35 parts. 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 Orange loop KiCad files?
From the sahko123/orange_loop_schematics repository on GitHub, at the commit this page was made from: the board is orange_loop.kicad_pcb and its schematic orange_loop.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Orange loop design in my own project?
Its repository states no licence, so its author keeps all rights: ask sahko123 before reusing the design.
