Questions
How big is the PECDR PCB?
It measures 85 × 54 mm and has 4 copper layers, 1.6 mm thick.
What parts does the PECDR use?
68 parts, built around the MAX485CSA+, L298N and B340A. 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 PECDR KiCad files?
From the pedro-ibs/trekking repository on GitHub, at the commit this page was made from: the board is circuito/PECDR-W/PECDR.kicad_pcb and its schematic anteriores-descontinuados/circuito/rasp-rpipico/trekking.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PECDR design in my own project?
Its repository states no licence, so its author keeps all rights: ask pedro-ibs before reusing the design.
