This Arduino pro mini uses over 600 times less power than a traditional pro mini, using a couple of simple changes which cost around $2 to make. An original 3.3V Arduino Pro Mini uses around 4500 microamps when running the standard blink sketch. By making the changes in this video, you can get this Arduino down to just 7 microamps, while keeping the same functionality.
Here's a full write-up on the modifications and results of each test - the-diy-life.com/making-an-ultra-low-power-arduino-pro
