Questions
What parts does the HappyDay Energy PCB use?
86 parts, built around the RAC03-3.3SGA. 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 HappyDay Energy PCB KiCad files?
From the BitKnitting/HappyDayNeighbors repository on GitHub, at the commit this page was made from: the board is HappyDay_Energy_PCB/HappyDay_Energy_PCB.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the HappyDay Energy PCB design in my own project?
Its repository states no licence, so its author keeps all rights: ask BitKnitting before reusing the design.
