Questions
How big is the Old School Motor Driver PCB?
It measures 149.9 × 100.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Old School Motor Driver use?
172 parts, built around the L7805, BC547, BC557 and BD139. 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 Old School Motor Driver KiCad files?
From the MilosSubotic/LPRS2_2024 repository on GitHub, at the commit this page was made from: the board is Automotive/Dynamometer/Old_School_Motor_Driver/HW/Old_School_Motor_Driver/Old_School_Motor_Driver.kicad_pcb and its schematic Automotive/Diesel_Generator/HW/Ctrl_on_Arduino_Motor_Shield/Ctrl_on_Arduino_Motor_Shield.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Old School Motor Driver 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).
