Questions
How big is the Hw alpha PCB?
It measures 100 × 100 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Hw alpha use?
171 parts, built around the AG9905-MTB, MAX232DR(AT), LM66100DCK and TPD1E05U06DPYR. 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 Hw alpha KiCad files?
From the Yexall/CPE-450.Capstone repository on GitHub, at the commit this page was made from: the board is Hardware/hw_alpha/hw_alpha.kicad_pcb and its schematic Hardware/IIS3DWB_breakout_beta/IIS3DWB_breakout_beta.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Hw alpha design in my own project?
Its repository states no licence, so its author keeps all rights: ask Yexall before reusing the design.
