Questions
How big is the Spruzzatore PCB?
It measures 75 × 35 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Spruzzatore use?
134 parts, built around the BME280, AO3400A, ABS06-32.768KHZ-T and LQH3NPN2R2MMEL. 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 Spruzzatore KiCad files?
From the felixmanfredi/SmartSprayer repository on GitHub, at the commit this page was made from: the board is PCB_Sansevero/HermaTech-main/PCB_Rev1/Spruzzatore.kicad_pcb and its schematic PCB_Sansevero/HermaTech-main/PCB_Rev1/BME280.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Spruzzatore design in my own project?
Its repository states no licence, so its author keeps all rights: ask felixmanfredi before reusing the design.
