OVERVIEW Larger than the original UNO board, this microcontroller has more flash memory, SRAM, EEPROM and I/O pins. This board is perfect for projects that require a lot of inputs/outputs or that require more complex programs that cannot fit into the smaller memory of the ATmega328P. New in R3 is added SCL/SDA pins next to AREF header and also added IOREF pin to power header. Built on the 'open-source electronics prototyping platform', and compatible with existing Arduino software lilbraries. HIGHLIGHTS • 8-bit AVR RISC-based microcontroller running at 16 MHz • 8x more flash and 4x more SRAM and EEPROM than the Uno • Connects to a computer via a standard USB cable • Flexible power source (USB 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 Mega 2560 designed by Arduino, and is released under the Creative Commons Attribution Share-Alike License.
