Questions
How big is the Sg90 driver PCB?
It measures 52.1 × 37.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Sg90 driver use?
32 parts, built around the NE555P, 74HC04D, 74HC595 and 74HC74D. 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 Sg90 driver KiCad files?
From the jacks-hax/Jerry repository on GitHub, at the commit this page was made from: the board is eda/drivers/sg90/sg90_driver.kicad_pcb and its schematic eda/drivers/sg90/sg90_driver.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Sg90 driver design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
