Questions
How big is the BB3plus mainboard PCB?
It measures 233 × 230.5 mm and has 4 copper layers, 1.61 mm thick.
What parts does the BB3plus mainboard use?
439 parts, built around the SN74LVC1G3157DCK, TPD2E001DRLR, TPD4E001DRLR and BAS316. 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 BB3plus mainboard KiCad files?
From the eez-open/eez-bb3plus repository on GitHub, at the commit this page was made from: the board is KiCad/BB3plus mainboard/BB3plus mainboard.kicad_pcb and its schematic Experimental/KiCad/BB3plus DVID adapter/BB3plus DVID adapter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the BB3plus mainboard design in my own project?
Its repository states no licence, so its author keeps all rights: ask eez-open before reusing the design.
