The world probably has enough ATMega32u4 (Arduino Leonardo) development boards. Some of them even put all the pins on a .100″ grid (unlike the original Arduino outline). But we feel that none of them is as easy to use on a breadboard as the BBLeo, which stands for breadboard Leonardo. The BBLeo is engineered to get you going quickly on a breadboard.
Just as in the Arduino Leonardo, the BBLeo has USB built in so you can just “plug and play”. Hint – all this great functionality that board developers like to brag about is usually built into the chips. We try to be honest about it.
