GPIO Relay Board, Push Buttons, Piface Replacement - Equivalent

This board contains the same components and offers the same possibilities as the PiFace

• 2 Potential-free relay, low voltage (not for 230V AC), normally open and normally closed contact
• 4 push buttons
• 8 digital input, with pullup
• 8 open-collector digital outputs (2 are shared with relays)
• Jumpers to adjust operation
• 2 practical terminal blocks for experiments
• Control LEDs on outputs
• Allows you to power the Raspberry PI with 5 volts, a jumper can be removed if you do not want this option

The Piface software can be used.

The board is slightly smaller than the old PiFace, so it is also suitable for use with the Raspberry Pi 4

Installation 

Python 3:
$ sudo pip3 install pifacecommon
$ sudo pip3 install pifacedigitalio

It is therefore an ideal cheap solution to connect your Rapsberry to the physical world ...
