1. Overview
The Baby Orangutan B-48 [http://www.pololu.com/catalog/product/1215], B-168 [http://www.pololu.com/catalog/product/
1216], and B-328 [http://www.pololu.com/catalog/product/1220] robot controllers are complete control solutions for small
robots. The small module includes a powerful Atmel ATmega48/168/328P microcontroller, two channels of
bidirectional motor control, a user potentiometer, 18 user I/O lines (16 of which can be used as general-purpose
digital I/Os and 8 of which can be used as analog input channels) that can be used to expand the system. A battery,
motors, and sensors can be connected directly to the module to create simple robots.
Note: This user’s guide applies only to the most recent Baby Orangutan B revision. The older,
discontinued Baby Orangutans [http://www.pololu.com/catalog/product/216] have green solder masks
while the new Baby Orangutan Bs have blue solder masks.

3. Schematic Diagram
The basic schematic of the Baby Orangutan B is identical to that of the larger Orangutan SV-328
[http://www.pololu.com/catalog/product/1227] and Orangutan LV-168 [http://www.pololu.com/catalog/product/775] robot
controllers. You can effectively build your own Orangutan SV-328 by adding a buzzer, LCD
[http://www.pololu.com/catalog/product/356], and pushbuttons as indicated in the Orangutan SV-328 schematic. This
design means software can be written for one device that will work on the other, provided the Baby Orangutan is
given matching hardware connections.
