Overview

The Orangutan X2 is the third release in Pololu’s line of Orangutan robot controllers. Like the original Orangutan and subsequent Baby Orangutan, the Orangutan X2 is designed to be a compact, high-performance control center for robotics and automation projects. The Orangutan X2’s two-board design allows the unit to maintain the compactness characteristic of the Orangutan line while offering substantially more electrical and computational power: the X2 can deliver up to a horsepower across two motor channels, and the twin-microcontroller architecture allows maximum access to the primary microcontroller, an Atmel ATmega644 AVR running at 20 MHz with 64 kB of program memory and 4 kB of SRAM. It has an outline smaller than a credit card, which makes it small enough to fit in a mini-sumo or small maze solver, yet it is powerful enough to run a 1/10th-scale monster truck. A battery, motors, and sensors can be connected directly to the module for quick creation of advanced robots.

Note: The motor driver (top) board pictured above is also available separately as a dual high-power motor driver.

The Orangutan X2 has two microcontrollers: an Atmel ATmega644 AVR for the main application, and an auxiliary ATmega168 that interfaces to most of the dedicated hardware on the X2 and serves as a programmer for the main processor. The two-microcontroller design simplifies multitasking by relieving the main processor of common tasks such as motor control and melody generation, and the approach also leaves the mega644 completely unencumbered, allowing the mega644 hardware, such as timers and interrupts, and most of the mega644 I/O lines to be used for your higher-level design. It also means you do not need an external programmer to use the Orangutan X2.
