Questions
How big is the CDFR2027-Carte Arduino PCB?
It measures 90 × 90 mm and has 4 copper layers, 1.6 mm thick.
What parts does the CDFR2027-Carte Arduino use?
85 parts, built around the TPS5450DDAR, DRV8870DDA, PCA9685PW and B540C. 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 CDFR2027-Carte Arduino KiCad files?
From the robotronik/CDFR2027-Carte-Arduino repository on GitHub, at the commit this page was made from: the board is CDFR2027-Carte-Arduino.kicad_pcb and its schematic 5v_dc.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the CDFR2027-Carte Arduino design in my own project?
Its repository states no licence, so its author keeps all rights: ask robotronik before reusing the design.
