This board is tailored to users who want a more 'build-it-yourself' approach as compared to the OSEPP Uno. Designed as a lower profile board (without headers) so you can mount your own headers specific to the functions you want, or solder directly. Built on the 'open-source electronics prototyping platform', and compatible with existing Arduino software lilbraries.

• 8-bit AVR RISC-based microcontroller running at 16 MHz
• About 2/3 the size of the OSEPP Uno board
• Flexible power source (lithium polymer battery or DC power)
• ICSP header for programming microcontroller
• Compatible with existing Arduino software libraries
• Compatible with the Ethernet and Motor Controller Shields

This board is based on the Arduino Pro designed by SparkFun Electronics, and is released under the Creative Commons Attribution Share-Alike License.
