Picture of Arduino Micro Power Expansion Shield

Recently I built a temperature logging device using an Arduino. It used a Real time clock, SD card writer and a temperature sensor. I did not need a bread board for testing as all the sensors were on breakout boards. All the devices needed 5V and ground to operate and I wanted to power them from the Arduino, but the Arduino only has one 5V outlet and three grounds. I had to get out a bread board just to have a way to attach all the power and grounds.

Wishing for a way to have more outputs available I came up with this Micro shield.

This is very simple to build and I think useful for doing some quick prototyping. You of course could use an empty shield or a bread board, but what fun is that?

Step 1: Parts

Picture of Parts

Parts can vary depending on what you have around.

You will need some headers Male, Female or both and a small piece of strip board.

Strip board is a prototype board with copper stripes down one side you could use the type with just dots around each hole if that is what you have just make sure they are all connected where needed.

The headers are just normal male pin headers, I used female headers too, but you can use all male or all female whatever you think is best. I like the male ones they don’t go bad if used too much.

IF you have some in colors they would be a good addition to the project, but all black is fine. I did not have any red so I used a red marker on some white ones I had.

You can buy black ones on Adafruit - 10 strips for about 5$US or on EBay if you want color and can wait.

Adafruit did not have the small short round female type header only the tall flat type. (Like on the Arduino) These are hard to cut to size but should work.

You can adjust the size of the board and make more pins or less but six holes seems plenty to me.

You also need a right angle header this allows you to solder the header to the board and have it stand vertical (unlike many shields). If you used straight headers to attach it to the Arduino it would have the pins facing down and be very hard to use.

Collected up the parts and made one myself! minus the coloured pins,thanks alot for the idea will help me alot in future arduino projects.

Good idea that likely make one myself,nice look on your shield though with the colour coding!

Hey there! I made you project and used it for my instructable

cool idea!!! giving power to all the sensors is really a pain...........really handy instructable!
