Questions
How big is the WxBackpack PCB?
It measures 20.4 × 45.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the WxBackpack use?
57 parts, built around the BMP180 and HTU21D. 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 WxBackpack KiCad files?
From the jrleeman/WxBackpack repository on GitHub, at the commit this page was made from: the board is KiCAD_Project/WxBackpack.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the WxBackpack design in my own project?
Its repository states no licence, so its author keeps all rights: ask jrleeman before reusing the design.
