Questions
What parts does the Servo Current Limiter use?
26 parts, built around the ARDUINO UNO R3, LM324 and IRF4905. 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 Servo Current Limiter KiCad files?
From the MilosSubotic/LPRS2_2023 repository on GitHub, at the commit this page was made from: the board is HW/Robot/Servo_Current_Limiter/Servo_Current_Limiter.kicad_pcb and its schematic HW/CNC/PB_Panel/PB_Panel.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Servo Current Limiter design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
