Questions
How big is the VibAndHeat Version1 PCB?
It measures 50 × 70.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the VibAndHeat Version1 use?
27 parts, built around the DHT11 and L7805. 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 VibAndHeat Version1 KiCad files?
From the achyutnar/therapyDeviceFYP repository on GitHub, at the commit this page was made from: the board is PCB Design/VibAndHeat_Version1/VibAndHeat_Version1.kicad_pcb and its schematic PCB Design/VibAndHeat_Version1/VibAndHeat_Version1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the VibAndHeat Version1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask achyutnar before reusing the design.
