Questions
How big is the MT7620N PCB?
It measures 146 × 127 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MT7620N use?
176 parts, built around the DLW21SN900SQ2, IP4220CZ6, AP2146SG and BLM21PG221SN1. 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 MT7620N KiCad files?
From the oshwlab/MakerRouter repository on GitHub, at the commit this page was made from: the board is hardware/MR808/MT7620N.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the MT7620N design in my own project?
Its repository states no licence, so its author keeps all rights: ask oshwlab before reusing the design.
