Questions
How big is the Robot PCB?
It measures 49.8 × 47.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Robot use?
41 parts, built around the NRF24L01, REG1117, MINI-USB-5P and RJ45. 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 Robot KiCad files?
From the koson/hometether repository on GitHub, at the commit this page was made from: the board is kicad/robot/r1/r2.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Robot design in my own project?
Its repository states no licence, so its author keeps all rights: ask koson before reusing the design.
