The PiRyte Mini ATX PSU allows you to power your Raspberry Pi and project boards using an inexpensive desktop power supply. Additionally, it enforces a controlled shutdown so that the Pi's operating system can properly close down without corrupting disk files.
- Uses inexpensive off the shelf ATX desktop supply. Works with both 20 pin and 24 pin connectors.
- Enables operating system to perform controlled shutdown and reboots to minimize disk file corruption.
- Back powers the Raspberry Pi with dedicated 5 VDC line.
- Screw terminals break out +12 VDC and +5 VDC for user projects.
- Provides a prototyping area with access to +12 VDC, -12 VDC, +5 VDC, +3.3 VDC, and Ground
- Conforms to the Raspberry Pi Foundation's HAT footprint.
- 40 Pin GPIO stacking header allows use of other HAT conforming boards.
- Comes as a DYI kit to keep costs low.
- Power up: LED pulsates slowly
- Reboot: LED pulsates slowly
- Shutdown: LED pulsates slowly until boot up script has ended then pulsates quickly for 10 seconds before shutting off power to the Pi
- Hard Shutdown: LED dims entire time push button is depressed. Turns off power after 10 seconds.
Why did you make it?
My projects often need multiple voltages in addition to the 3.3 VDC or 5 VDC supplies usually provided by the Raspberry Pi. Existing ATX type desktop power supplies provide the kind of power that I can use. Additionally, I needed my board to be a HAT conforming board so that I can build controller stacks using the other boards I designed as well as third party boards. I am very particular in using stacked configurations because a stacked configuration is physically and electrically more robust. Finally, I wanted to mitigate the chance of file corruption by just turning off my Raspberry Pi without doing a controlled shutdown. This board allows me to do this.
