Definitions library for RPi.GPIO, no implementation(used only for IntelliSense)
pip install RPi.GPIO-def
If you like to develop in IDEs like PyCharm you would like some sort of autocompletion. In order to have it, you should install RPi.GPIO and PyCharm will do it's magic and provide autocompletion for you, but that's never that easy(especialy under Windows). By using this library, you will have it, without the frustating setup.
NO IMPLEMENTATION WHATSOEVER. You can't use RPi.GPIO under Windows/Linux anyway, it is meant to work only on the Raspberry Pi
