Digital input/output module, 2 relays, 4 push buttons, Piface replacement for Raspberry Pi

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 on older Raspberry Pis; however, the pifaceio Python module is recommended for all versions of Raspbian (tested on Trixie).

The board is slightly smaller than the older PiFace, so it's also compatible with the Raspberry Pi 4.

This makes it an ideal, inexpensive solution for connecting your Raspberry Pi to the physical world, or for teaching.

Installation

Python 3 (older)
$ sudo pip3 install pifacecommon
$ sudo pip3 install pifacedigitalio

Python3 (Debian Trixie), faster easy install
$ sudo pip3 install pifaceio

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