Questions
How big is the Espboard PCB?
It measures 38 × 66.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Espboard use?
53 parts, built around the AOCA32116E. 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 Espboard KiCad files?
From the OlinSTEP/2023-EE repository on GitHub, at the commit this page was made from: the board is board_rev2/espboard/espboard.kicad_pcb and its schematic board_rev2/espboard/espboard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Espboard design in my own project?
Its repository states no licence, so its author keeps all rights: ask OlinSTEP before reusing the design.
