Questions
How big is the CTRL PCB?
It measures 121.1 × 136.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the CTRL use?
146 parts, built around the IR2110L4, LM2576HVS-ADJ, LM1117S-ADJ and IRF1407PBF. 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 CTRL KiCad files?
From the krish-iitbhu/Single-Motor-PCB-CONTROLLER- repository on GitHub, at the commit this page was made from: the board is CTRL.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the CTRL design in my own project?
Its repository states no licence, so its author keeps all rights: ask krish-iitbhu before reusing the design.
