Questions
How big is the P2 Kevinbot Board PCB?
It measures 196.5 × 95.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the P2 Kevinbot Board use?
125 parts, built around the PCA9685PW, DS18B20, TC4427EOA and FDN337N. 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 P2 Kevinbot Board KiCad files?
From the Kevinbot-Robotics/kevinbot_p2_board repository on GitHub, at the commit this page was made from: the board is P2 Kevinbot Board.kicad_pcb and its schematic P2 Kevinbot Board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the P2 Kevinbot Board design in my own project?
Its repository publishes it under the CERN-OHL-S-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
