VERY IMPORTANT!!! - PLEASE DON'T USE OTHER POWER SOURCES WHEN USING THIS POWER SUPPLY EXPANSION BOARD!!!!!
OTHERWISE YOU WOULD BLOW UP YOUR PI!!!!!
Power up your Raspberry Pi in a cool different way!
Again, let's talk about the Raspberry Pi power supplies.
Do you have a lot of different power supplies in your tool box? I do. As you know, the Raspberry Pi needs a 5V 700mA, micro-USB socket power supply. Unfortunately most of power supplies output 9V or 12V, and only have Jack sockets. So we can't use them, what a shame!
And that's why the Raspberry Pi Power Supply in our store is popular. We had to pack many of them everyday. This brings us an issue: We test every power supply before we sell it so you know what happened, the micro-USB power socket on the Pi is getting loose and almost damaged. OK, if you don't plug and unplug the power cable from the Pi 20 times a day, you probably don't need to worry about that. But you might have noticed another thing that is annoying: the Pi doesn't have a power switch. When you need to turn on/off or reboot your Pi, I guess you have to use the switch on the power point(I do that) or unplug/plug the power supply from the power point. It's alright I reckon, not a big issue. Just a little bit inconvenient.
Before we started selling our Raspberry Pi Power Supply, we bought a lot of power supplies to test. If we ignore the output voltage, the current, the brand or the manufacturer of these power supplies, then you know what the same big issue of them is? The output ripple voltage is too high. Some of them even more than 100mV. Can you believe it? It's horrible!
Another thing you might have to think about: If you use your Pi as your robot controller, how are you gonna power it? The Pi needs 5V DC, whereas your motors or other devices on the robot might use 12V DC, so how to choose the power source? How to get different voltages from one battery? That wouldn't be very tricky but you really have to think about it.
Now have a look at this: we made this power expansion board - "echidna" for the Raspberry Pi. Let's see the features:
Currently we have three different versions of echidna. You can compare them:
* A special part for the case is needed to fit the "echidna" board. All of our Pi Case 2.0 Premium customers can get this part for free. Please message us when you buy this "echidna" board.
