The ATX-Pi was born out of the need to control an ATX power supply while simultaneously powering the Raspberry Pi from the power supply. The ATX-Pi adds "ACPI" type functionality to the Pi (automatic hardware based shutdown).
This item is being sold as a kit, some soldering experience is recommended. You should also be comfortable installing packages and scripts on your Pi, otherwise the Arduino won't be able to signal for a shutdown! GPIO ribbon cable and USB power cable not included.
On the board is an Arduino clone powered on the 5V Standby rail. All unused digital/analog and serial pins are broken out, as well as the unused pins on the Pi ribbon cable. Also broken out are the main PSU voltages via the screw terminals you see next to the ATX connector (terminals are rated for 3A). Any standard case switch set will work with this board so it will easily integrate your Pi project into a PC case. The hard drive and power LEDs will also plug into the board to give you indication on your case of the Pi's status.

My personal need arose when I became involved with ASIC Bitcoin mining. I needed a convenient way to safely shut off my Pi and my Power Supply for those times when I need to clean or otherwise move my mining rig.
Another possible use case would be someone who needs to power a large array of LEDs in an internet capable appliance. There is a large amount of pins available on the board for not only the Pi but the Arduino clone as well. Not only could you control LED lighting but also water pumps (via Relay), humidity sensors, really anything else your project requires, because you will certainly have enough power.

Hi! I'm KD8SSF, an amateur radio (mostly APRS) and DIY electronics enthusiast. My interest in amateur radio began when I started planning my High Altitude balloon project. Seeing that it wasn't legal to track a payload with a cell phone, I turned to the HAM community for the knowledge and experience to take on such a feat. Since then I have grown my knowledge in many different areas and am always looking for a new challenge.
