Digital Input & Output

The Raspberry Pi has several digital IO (input and output) pins which operate at 3.3 volts but will be damaged if you try to connect 5 volt devices direct to the Raspberry Pi.

Our range of IO expansion boards allow you to connect 5 volt devices to your Raspberry Pi and the stacking design of the IO Pi Plus allows you to add up to 128 additional IO ports to your Raspberry Pi.

We sell the following digital input and output boards for use with the Raspberry Pi and other compatible single-board computers.
