Questions

How big is the IOB V3 PCB?

It measures 80 × 140 mm and has 4 copper layers, 4.69 mm thick.

What parts does the IOB V3 use?

280 parts, built around the STM32G474MET3, MCP2562FD-E/P, CD74HC4067M and W25Q256JV. 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 IOB V3 KiCad files?

From the SpaceTeam/Lamarr_IOB_V3 repository on GitHub, at the commit this page was made from: the board is IOB_V3.kicad_pcb and its schematic 24V_to_5V-12V_SMPS.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the IOB V3 design in my own project?

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