The Baby Orangutan B-48 is a very compact but complete robot controller, packing a high-performance AVR microcontroller and two motor drive channels in the same 24-pin form factor as competing units that include just a microcontroller. This version includes Atmel’s ATmega48 microcontroller with 4 KB of program memory and 512 bytes of RAM.

Overview

The Baby Orangutan is a complete control solution for small robots, all packed into a tiny 1.2" x 0.7" 24-pin DIP package. Its compact design eliminates bulkier components such as the LCD and switches while retaining the most essential features of the Orangutan robot controller line: a programmable ATmega48 or ATmega328P AVR microcontroller and a dual H-bridge for direct control of two DC motors. This integrated motor driver sets the Baby Orangutan B apart from similarly-sized microcontroller boards from other manufacturers. Two on-board indicator LEDs, a trimmer potentiometer, a 20 MHz resonator, and reverse battery protection round out the basic hardware features of the Baby Orangutan.

The removal of the larger Orangutan components also allows for a significantly improved manufacturing process that allows Pololu to offer the Baby Orangutan B at a very affordable price. Because the Orangutans are based on Atmel’s powerful AVR microcontrollers, the Orangutans deliver significantly higher performance than other similar controller boards. The availability of free development software, such as the Atmel Studio IDE and the WinAVR GCC C/C++ compiler, and low-cost programmers, such as the Pololu USB AVR programmer, make the Baby Orangutan B a truly outstanding value. We offer a combination deal that lets you save when you buy a USB AVR programmer with your Baby Orangutan.

For those not necessarily interested in robotics, the Baby Orangutan B is also a great introduction to the AVR microcontrollers because of its size and price. All you need to get started is a low-cost programmer and a power source. You can fit a substantial design even on a small breadboard since you won’t need the space for basic components such as the voltage regulator and resonator. The source code for several sample projects is available under our resources tab; these examples are intended to help you get up and running quickly with your new AVR-based controller.
