Questions
How big is the MAVRIC Main PCB?
It measures 102.4 × 98.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MAVRIC Main use?
66 parts, built around the STM32F401RCT6, AOZ1280CI, INA125U and SN75176BDRG. 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 MAVRIC Main KiCad files?
From the ISU-MAVRIC/MAVRIC_Main repository on GitHub, at the commit this page was made from: the board is Hardware/Main Board.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the MAVRIC Main design in my own project?
Its repository states no licence, so its author keeps all rights: ask ISU-MAVRIC before reusing the design.
