• Clear prints on the female header connector, more precise and easier to use the wire
• Wses an ATMega16U2 chip instead of the ATMega8U2 chip for faster transfer rates and more memory
• Control using ATMEL ATMEGA328P chip (the same with Arduino UNO R3)
• 100% compatible with the Arduino IDE
• RoHS Compliant
