Questions
How big is the Power test PCB?
It measures 100 × 70 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Power test use?
35 parts, built around the RT8289GSP, AMS1117-3.3, BQ25886RGE and 100UF 10V 4*7. 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 Power test KiCad files?
From the Gex-devs/miniHexa repository on GitHub, at the commit this page was made from: the board is miniHexa_PCB/power_test/power_test.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 Power test design in my own project?
Its repository states no licence, so its author keeps all rights: ask Gex-devs before reusing the design.
