Questions
How big is the FilaBoss control PCB PCB?
It measures 102.9 × 87.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the FilaBoss control PCB use?
60 parts, built around the R-78B12-2.0, R-78E5.0-0.5, INA219AID and IRLZ44N. 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 FilaBoss control PCB KiCad files?
From the ronisillman/FilaBoss repository on GitHub, at the commit this page was made from: the board is PCB/FilaBoss_control_PCB/FilaBoss_control_PCB.kicad_pcb and its schematic PCB/FilaBoss_control_PCB/FilaBoss_control_PCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the FilaBoss control PCB design in my own project?
Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
