Mulitifunctional Board Explore 500 for Raspberry Pi
Connecting peripherals, devices, etc. to the Raspberry Pi via the GPIO is not always the most elegant solution – the easy-to-use is this expansion board.
This is simply plugged onto the GPIO connector of the Raspberry Pi, and the peripherals can be conveniently connected via their own connectors. In addition, the board provides a display port for standard LCD modules with HD44780 controllers, a debug USB interface with the CP2102, and a real-time clock (RTC) with battery backup.
