An Atmel ATMega328P (Arduino compatible) microcontroller running at 16 MHz and selectable voltage.

Atmel's line of powerful (but not power hungry) processors known as AVRs are now the defacto standard for hobbyists, students and engineers when searching for 8-bit processors. These RISC MCUs are packed with features that make them ideal for robotics, controls and embedded solutions.

This particular AVR has been chosen to due it's popularity and large built-in peripheral set. The board can be used by itself with a breadboard or as a an add-on in a BoardX system where I2C, SPI, and UART are automatically routed and connected to the other add-ons. The reset button on BoardX Motherboard is connected to the processor's reset line, and the USB reset/programming feature allows you to use the Arduino SDK to program it.

Features Include:

• I/O sockets for all of the chip's pins
• Built-in voltage switch to toggle MCU power between 3.3V and 5.0V
• Works transparently with the Arduino SDK and comes with the Arduino bootloader pre-installed
• USB Programmable
• Has the standard 6-pin header for use with Atmel's ISP Mk-II Programmer
• Includes a 16 MHz external oscillator for higher speed operation
  

Note to buyers:
Use your AVR-X Processor Add-on with BoardX or any standard breadboard.

What is BoardX?

BoardX is a collection of electronic circuit boards that stack on top of one another to share resources, communicate, and extend the functionality of one another. This system is built on the BoardX Motherboard that acts as both an electrical and structural foundation.

What add-on modules are available?

• FRAM-X - Non volatile memory
• ADC-X - 8 channel converter
• XBee-X - GPS + Wifi + Zigbee + Bluetooth compatible
• AVR-X - Atmega328P, with Arduino
• PROTO-X - A perforated soldering add-on for creating your own add-ons
