Questions
How big is the MrBeamShield PCB?
It measures 78.9 × 53.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MrBeamShield use?
98 parts, built around the LM3406MH, NC7WZ08K8X, MBRS540T3 and BSS138. 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 MrBeamShield KiCad files?
From the mrbeam/Mr-Beam-Shield repository on GitHub, at the commit this page was made from: the board is MrBeamShield/MrBeamShield.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the MrBeamShield design in my own project?
Its repository states no licence, so its author keeps all rights: ask mrbeam before reusing the design.
