Questions
How big is the MiniLFMv2 solderjoint smaller PCB?
It measures 47 × 24 mm and has 4 copper layers, 1 mm thick.
What parts does the MiniLFMv2 solderjoint smaller use?
135 parts, built around the LTC3218EDDB#TRMPBF, MAX14574EWL+, MT9P031I12STM-DP1 and SC189ZULTRT. 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 MiniLFMv2 solderjoint smaller KiCad files?
From the vazirilab/MiniLFMv2 repository on GitHub, at the commit this page was made from: the board is Electrical/MiniLFMv2_headdevice_kicad/MiniLFMv2_solderjoint_smaller.kicad_pcb and its schematic Electrical/MiniLFMv2_headdevice_kicad/MiniLFMv2_solderjoint_smaller.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MiniLFMv2 solderjoint smaller design in my own project?
Its repository states no licence, so its author keeps all rights: ask vazirilab before reusing the design.
