The Baby Orangutan B-328 is a very compact but complete robot controller, packing a high-performance ATmega328P AVR microcontroller (with 32 KB of program memory and 2 KB of RAM) and two motor drive channels in the same 24-pin form factor as competing units that include just a microcontroller. You can connect your battery, sensors, and motors directly to this small module to make a miniature robot, or you can use the Baby Orangutan as an auxiliary controller in larger robots.
