Questions
What parts does the SolarFlowmeterMonitor use?
18 parts, built around the XL6009, XC6206P332MR and AO3413. 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 SolarFlowmeterMonitor KiCad files?
From the ravilez/KiCad-Models repository on GitHub, at the commit this page was made from: the board is SolarFlowmeterMonitor/SolarFlowmeterMonitor.kicad_pcb and its schematic LiPO_SharePower/LiPO_SharePower.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the SolarFlowmeterMonitor 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).
