Questions
How big is the Mt7628v1 PCB?
It measures 90.5 × 68.3 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Mt7628v1 use?
201 parts, built around the MT7628NN, SP3232EEN, MP1470-MS and W25Q256JVEIQ. 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 Mt7628v1 KiCad files?
From the findasifrahman/mt76-- repository on GitHub, at the commit this page was made from: the board is mt7628v1.kicad_pcb and its schematic Pheripheral.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Mt7628v1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask findasifrahman before reusing the design.
