This morning a new one came our way. [Johan Kanflo]’s AAduino is an Arduino clone with an onboard RF module that fits within the form factor of an AA battery.

Now affix the lid to the box, stick in some batteries, and play with your new Arduino-powered coin box. Hours of fun are now to be had! Enjoy it.

An amusing aspect of the board is how Kanflo attached battery terminals, including a spring, on the board itself. This allows the AAduino to slot into the battery slot like a regular battery.

A Swedish software engineer makes a wireless Arduino clone called AADuino. The system fits neatly within the form factor of an AA battery.

It only applies to certain microcontrollers, but he provides example Arduino code showing how handy this can be for battery-powered projects.
