Actual voltages, amperage

The international version of the Raspberry PI switching PSU seems to be worth the bucks.

I'm using a so-called "DC 9V-35V to 3-6V Adjustable 4-USB Step-down Power Supply Converter Board Module" from eBay - has four USB outlets, plus a screw terminal output, and you can fine-tune the output to your needs. I found this unit perfect for my needs as a lot of my electronics stuff is running from a 12v solar charged setup, so needs to be 11v - 15v powered! Big Grin

The adafruit stuff is great, especially their 5v power supplies, as they also fine-tune the output voltages so they are slightly high, to try and overcome poor wiring and voltage sag on longer runs.
