Axon II microcontroller for the robotics hobbyist

The Axon II was developed for robots that go beyond the basics. With the Axon II, you will no longer need to worry about not having enough I/O as it has 58 for you to use. You will never be wanting of UART, as there are 3 directly available, with a 4th used for a USB connection directly to your PC. A total of 16 ADC ports for all of your sensors. A bootloader is pre-installed so no hardware programmer is needed. Lastly, extensive source code and tutorials have been developed to make it easy enough for a beginner yet still powerful enough for an expert.

More specifically, the Axon II is the best microcontroller on the market for multi-limbed robots such as bipeds, spiders, and robot arms. Unlike many other robot microcontrollers on the market, no additional messy breadboard wiring or expensive shields are required to make your robot. It's 100% plug-n-play - no external power buses required to plug in servos or sensors, literally taking minutes to set up.

The Axon II uses the powerful ATmega640 as its processor, which has typically 4x more memory than other controllers on the market (see specifications below).

Lastly, at 34 grams (a typical 9V battery weighs 40g), the Axon II is the smallest and lightest of any other comparable full-featured microcontroller on the market.
