Orangutan X2 with VNH3
 

The Orangutan X2, the most powerful member of Pololu’s line of Orangutan robot controllers,
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 ATmega1284P AVR running at 20 MHz with 128 KB of program memory and 16 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.
The board features an integrated dual motor driver capable of delivering
14 A continuous (30 A peak) per channel, a buzzer for simple sounds and music, an
LCD port with optional 20×4 character LCD, three user pushbuttons, five user LEDs, a built-in programmer and USB
connectivity, and more; a battery, motors,
and sensors can be connected directly to the module for quick creation of advanced, powerful 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: a user-programmable Atmel ATmega1284P
AVR for the main application, and an auxiliary ATmega328P that is pre-programmed to
interface with most of the dedicated hardware on the X2 and serve as an AVR ISP
programmer for the main processor, which means that no external programmer is required.
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 almost
all of the mega1284 hardware peripherals, such as timers and interrupts,
and most of the mega1284 I/O lines to be used for your higher-level design.

The Orangutan X2 is compatible with freely available development software for Atmel’s
AVR microcontrollers, including Atmel’s AVR/Atmel Studio, the WinAVR GCC C/C++ compiler,
and AVRDUDE. We provide an extensive set of software libraries that make it easy to interface with
all of the integrated hardware, including the auxiliary microcontroller. Using these libraries,
it takes just a few simple lines of code to write to the LCD, read button presses,
drive motors, and control servos. These libraries come with a number of sample programs
that demonstrate how to use the various components on the Orangutan X2.
