Nick Sayer shared his Pi Power project on the Show & Tell a couple of weeks ago!

Pi Power is the power supply that the Raspberry Pi should have come with!

Pi Power is a switching power supply for the Raspberry Pi. It plugs into the GPIO header, and has an extra tall stacking header to keep the board out of the way of the display connector and facilitate plugging something else into the GPIO connector as well.

It has a 2.1mm barrel connector that will accept 6-15 VDC. It supplies up to 2 amps of 5 volts. At supply voltages over 9 volts, it has a ripple of 25 mV P-P. At lower supply voltages, the ripple goes up to 45 mV.

At 12 volts, a Raspberry Pi with a WiFi module, camera and a keyboard will consume around 250-300 mA. A 10 watt 9 volt power supply is the ideal power source, but really any 10 watt source will do.

What makes it special?

There are other power supplies out there for the R-Pi. But I think this one is the best. The R-Pi will fit in the bottom half of most cases with it connected. You can mount it externally and connect it with a GPIO cable if you prefer. It supplies more than enough power for both the R-Pi and any reasonable collection of peripherals you might choose to connect. For model B Pis, this includes possibly using high (up to 500 mA) current USB devices without an external powered hub. It’s small, powerful, accepts a wide range of input voltages….
