Questions
How big is the LMR1405001 PCB?
It measures 52.8 × 52.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LMR1405001 use?
24 parts, built around the STPS5L60. 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 LMR1405001 KiCad files?
From the mlab-modules/LMR1405001 repository on GitHub, at the commit this page was made from: the board is hw/sch_pcb/LMR1405001.kicad_pcb and its schematic hw/sch_pcb/LMR1405001.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the LMR1405001 design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
