Questions
How big is the Myo hub PCB?
It measures 57.5 × 57 mm and has 2 copper layers, 1.67 mm thick.
What parts does the Myo hub use?
45 parts, built around the AD7124-8BBCPZ-RL7. 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 Myo hub KiCad files?
From the trupples/thesis repository on GitHub, at the commit this page was made from: the board is hardware/myo-hub/myo-hub.kicad_pcb and its schematic hardware/ad4114-wings/ad4114-wings.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Myo hub design in my own project?
Its repository states no licence, so its author keeps all rights: ask trupples before reusing the design.
