Questions
How big is the MEB PCB?
It measures 49.8 × 49.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MEB use?
45 parts, built around the NCP1117LPST33T3G-MS, FSM2JSMA, 0466002.NRHF and TLW-104-05-T-D. 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 MEB KiCad files?
From the ncsurobotics/SW8E-MEB repository on GitHub, at the commit this page was made from: the board is MEB.kicad_pcb and its schematic MEB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MEB design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
