I've expanded the Raspberry Pi beyond a simple Single Board Computer to allow it to better interface with other hardware in an industrial setting.

Pi Supply is an add-on board for the Raspberry Pi adding an on/off power switch and power managment features.

Solar Panle for Raspberry Pi

Got a project that means your Raspberry Pi needs to be outside? Take advantage of solar power to run you Raspberry Pi.

The Raspberry Pi is equipped with a GPIO port (general purpose input/output) which allows programs to communicate directly to connect devices and circuitry. If you are interested in tinkering with electronics or expanding the capabilities of the Raspberry Pi then the GPIO is the gateway to your projects.
