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.

Documentation and other information
User’s guide for the Pololu Baby Orangutan B-48, B-168, and B-328 robot controllers.
This guide explains how to get started programming your Orangutan or 3pi Robot in Windows, Linux or Mac OS X. It covers setting up an AVR development environment (Atmel Studio for Windows users), installing the Pololu AVR C/C++ Library, and setting up the Pololu USB AVR Programmer.
Information about installing and using the C/C++ libraries provided for use with Pololu products.
A reference to commands provided in the Pololu C/C++ and Arduino libraries for the AVR.
Guide for programming Orangutans and the 3pi robot from the Atmel’s older AVR Studio 4 IDE. It covers installing the Pololu AVR C/C++ Library, and setting up the Pololu USB AVR Programmer.
Guide to making the Arduino IDE compatible with the 3pi robot and the Orangutan SV-328, Orangutan LV-168, and Baby Orangutan B robot controllers, including Arduino libraries for interfacing with all of their on-board hardware.
Detailed information about the 3pi Robot, Orangutan SV-328/168 and LV-168, and Baby Orangutan B motor drivers, including truth tables and sample code.
A guide for implementing the SMBus (I²C-compatible) protocol for the MLX90614ESF temperature sensor on the AVR-based Orangutan robot controller series. The guide includes sample code for taking temperature readings.

- AVR Studio 4 demo project #1 for the Orangutan SV-168 and LV-168 (14k zip)
- C code for the mega168: This project demonstrates the fundamentals of using I/O lines on a mega168. Each line of the source code is commented, and there is a short tutorial in comments at the start of main() on using AVR I/O and on C bit-logic. The program will alternately flash the two user LEDs until you ground the general-purpose I/O pin PD0 (the right-most of the eight user I/O lines at the top of the board). Grounding pin PD0 will cause the program to pulse the buzzer pin instead of the LED pins, causing the buzzer to play a note. While intended for use on the Orangutan SV-168 and LV-168, this program will run on the Baby Orangutan B-168 and can serve as a useful example on how to use the ATmega48/168 I/O lines. It will run on the Baby Orangutan B-328 with some minor modifications.
- LSM303DLM Orangutan example project (5k zip)
- This sample program shows how to use an LSM303DLM 3D compass and accelerometer carrier with an Orangutan robot controller to build a tilt-compensated digital compass. The AVR Studio project is set up for an ATmega328P microcontroller, but it will work on other Orangutans with simple changes to the project configuration.
