Questions
How big is the MB1814 PCB?
It measures 70 × 82.5 mm and has 4 copper layers, 1.63 mm thick.
What parts does the MB1814 use?
210 parts, built around the ESDALC6V1W5, ECMF02-2AMX6, LD39100PUR and ST730M33R. 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 MB1814 KiCad files?
From the lorenalam/TFG repository on GitHub, at the commit this page was made from: the board is Hardware/ImportKiCAD_2/MB1814.kicad_pcb and its schematic Hardware/PCB_TFG_v1.2/PCB_TFG_v1.2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MB1814 design in my own project?
Its repository states no licence, so its author keeps all rights: ask lorenalam before reusing the design.
