This is a downsized version of the Uno board with much of the same functionality. The main workhorse is still the ATmega328P; however, the number of analog pins has gone up from four to eight. The other difference is the lack of a DC power connector. 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
• Single Mini-USB connector for both power and serial communication
• Form factor is breadboard friendly
• Less than 1/3 the size of the OSEPP Uno
• Two extra analog input pins compared to the OSEPP Uno
• Compatible with existing Arduino software libraries
