Questions
How big is the Athena PCB?
It measures 344.7 × 123.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Athena use?
557 parts, built around the STM32F401RCT6, AT24C256C-SSHL-T, SGM2007-3.3XN5/TR and TXS0101DRLR. 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 Athena KiCad files?
From the BenjaminJAnderson/Orthodox repository on GitHub, at the commit this page was made from: the board is Hardware/PCB/references/Athena-main/kicad_files/athena.kicad_pcb and its schematic Hardware/PCB/Orthodox.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Athena design in my own project?
Its repository states no licence, so its author keeps all rights: ask BenjaminJAnderson before reusing the design.
