Questions
How big is the Echo PCB?
It measures 51.1 × 50 mm and has 4 copper layers, 1.61 mm thick.
What parts does the Echo use?
56 parts, built around the TLV1117-33DCY and ICS-52000. 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 Echo KiCad files?
From the kashishkebab9/echo repository on GitHub, at the commit this page was made from: the board is pcb/echo.kicad_pcb and its schematic pcb/echo.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Echo design in my own project?
Its repository states no licence, so its author keeps all rights: ask kashishkebab9 before reusing the design.
