Questions
How big is the Portero bot v2 PCB?
It measures 117.5 × 104.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Portero bot v2 use?
75 parts, built around the CH340C, ESP32-WROOM-32E-N16, W5500 and 2N2222A. 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 Portero bot v2 KiCad files?
From the Willis75/portero-bot-hardware repository on GitHub, at the commit this page was made from: the board is kicad/portero-bot-v2.kicad_pcb and its schematic kicad/portero-bot-v2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Portero bot v2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask Willis75 before reusing the design.
