Questions
How big is the MiniHexa PCB?
It measures 94 × 65.9 mm and has 4 copper layers, 1.6 mm thick.
What parts does the MiniHexa use?
82 parts, built around the SN74LVC1G125DBV, SN74LVC1G126DBV, RT8289GSP and AMS1117-3.3. 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 MiniHexa KiCad files?
From the Gex-devs/miniHexa repository on GitHub, at the commit this page was made from: the board is miniHexa_PCB/miniHexa.kicad_pcb and its schematic miniHexa_PCB/18_pwm_interface.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MiniHexa design in my own project?
Its repository states no licence, so its author keeps all rights: ask Gex-devs before reusing the design.
