## Description

Last time we connected a pie to an electric motor, it made a mess of the kitchen. It turns out that raspberry pie is still a challenge for motors… *Raspberry Pi*, on the other hand, can totally hook up to all kinds of controls and sensors thanks to the PiFace Digital expansion board!

 The PiFace Digital plugs directly into the GPIO port on your Raspberry Pi and adds a whole load of input and output capability. You can detect switch states, drive motors, move actuators, blink LEDs… you know, all the good stuff! Program it any way you want but there’s existing documentation for Python *and* Scratch! All of the input and output connectors are screw terminals, making it really easy to wire your Pi to all kinds of external systems. If you want to get an interactive project off the ground quickly with Raspberry Pi, the PiFace Digital is a great way to start.

**Features:**

- Plugs directly onto the Raspberry Pi GPIO socket
- Fits Directly over the Raspberry Pi and within the Raspberry Pi’s footprint
- 2 Changeover Relays
- 4 Tactile Switches
- 8 Digital Inputs
- 8 Open-Collector Outputs
- 8 LED Indicators
- Easy to program in Python, Scratch and C
- Graphical Emulator and Simulator
- Relays can be used to switch voltages up to 20V (Max) or currents up to 5A (Max)
