Easy to integrate
Used for a school project. Very easy to set up with Raspberry Pi GPIO pins.

Compact and useful
Good module but pins are close together. Works well otherwise for my lighting project.

Needs pull-up resistors
Had noise issues until I added external resistors. Works now but documentation was sparse.
