Arduino 2-Digit 0.5″ Common Cathode 7 Segment Display Module

This is an Arduino compatible board for creating 2 Digit Display projects. The circuit operates with 5V DC, Connector CN1 is provided for bootloader programming and Arduino firmware upload. A new Atmega328 chip requires a bootloader and Arduino firmware programming, Connector CN1 helps you with both functions. Follow the link below to learn more about programming using Arduino. Arduino code is available as a download to test the board.
