Questions

How big is the MCU Unit PCB?

It measures 134 × 100 mm and has 4 copper layers, 1.6 mm thick.

What parts does the MCU Unit use?

158 parts, built around the LAN8742A-CZ, MAX3485ED, FT232RL and TPS62933DRL. 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 MCU Unit KiCad files?

From the camerachan/F767ZI_TestBench_sch repository on GitHub, at the commit this page was made from: the board is MCU_Unit.kicad_pcb and its schematic 7seg.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the MCU Unit design in my own project?

Its repository states no licence, so its author keeps all rights: ask camerachan before reusing the design.
