On this pcb there’s also a header for connecting the ON/OFF push button. A total of 9 switches in a 3×3 matrix wired to the controller connector J4. Here you find the schematics.
To open and close the cover I’m using a 5W Maxon DC motor (110124) with a 64:1 gearhead (110483). It only needs 1.5 turn to displace the cover over 13cm. With this motor/gearhead it takes about 1.2 seconds to open/close the cover.
The inputs (IN1 and IN2) are controlled by the controller pcb (J10).
