Questions
How big is the MTA PWM v3 PCB?
It measures 95.9 × 90.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MTA PWM v3 use?
29 parts. 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 MTA PWM v3 KiCad files?
From the UWCubeSat/HS2-ADCS-PCB repository on GitHub, at the commit this page was made from: the board is MTA-PWM_v3/MTA-PWM_v3.kicad_pcb and its schematic MTA-PWM_v2.1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MTA PWM v3 design in my own project?
Its repository states no licence, so its author keeps all rights: ask UWCubeSat before reusing the design.
