The PiRyte Mini ATX PSU allows you to power your Raspberry Pi and project boards using an inexpensive desktop power supply. It also enables a controlled shutdown of the Pi to mitigate file corruption.
This board allows the Raspberry Pi to control up to eight Circuitron type stall motors with its on-board MCP23S08. Can be controlled by custom code in language of your choice or by Breezy4Pi, another project I created.
