Raspberry Pi Project Power Supply
By Nwazet (PIPOWER)
This power supply is designed to provide the Raspberry Pi with a clean and stable power source from a 9V wall-wart such as 9V 1A Power Supply. As you may know, the Raspberry Pi can become unstable when used with power-hungry USB devices and this power supply will provide the head room needed to keep your setup running smoothly.
For Raspberry Pi hackers out there, this power supply also features two additional voltage regulators, respectively outputting 800mA at 3.3v and 5V on power rails conveniently accessible through a vertical JST connector, as well as a standard 0.1" pin header.
