Description: Named after its designer, Gert van Loo, the Gertboard is an IO expansion board for the Raspberry Pi with a lot of flexibility.
Plug the Gertboard into the GPIO header on your Raspberry Pi and you're ready to start detecting and responding to events in the real world. Jumper wires (called "straps") and pin jumpers are used to reconfigure the board in any number of ways. Whether you need to detect button presses or analog voltages, control motors or relays, the Gertboard is the ultimate tool for exploring the Raspberry Pi's full I/O potential!
