Questions
How big is the Stack PCB?
It measures 80 × 80.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Stack use?
12 parts, built around the DHT11, MPU-6050 and RFM95W-915S2. 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 Stack KiCad files?
From the 20lohith05/stack repository on GitHub, at the commit this page was made from: the board is MainBoard/MainBoard/MainBoard.kicad_pcb and its schematic MainBoard/MainBoard/MainBoard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Stack design in my own project?
Its repository states no licence, so its author keeps all rights: ask 20lohith05 before reusing the design.
