Questions
How big is the Controls Leader PCB?
It measures 79.3 × 97.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Controls Leader use?
187 parts, built around the CP2102N-A01-GQFN24, RI3-1205S, CDSOT23-T24CAN and IRLML0030. 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 Controls Leader KiCad files?
From the lhr-solar/Controls-LeaderPCB repository on GitHub, at the commit this page was made from: the board is Controls-Leader.kicad_pcb and its schematic CAN.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Controls Leader design in my own project?
Its repository states no licence, so its author keeps all rights: ask lhr-solar before reusing the design.
