SparkFun 7-Segment Serial Display - Red
The SparkFun 7-Segment Serial Display combines a classic 4-digit 7-segment display and an ATMega328 microcontroller allowing you to control every segment individually using only a few serial lines.
The Serial 7-Segment Display can be controlled in one of three ways: Serial TTL communication, SPI serial communication or I2C serial. You can even program it for stand-alone operation since the ATMega328 comes pre-loaded with the Arduino bootloader! There is also an FTDI header on board and Sparkfun have provided a hardware profile for the Arduino IDE to make it even easier to program.
Sparkfun have made some layout changes to this design as well which will make it easier to incorporate these into your project. They have moved the power and I2C pins to the sides of the board such that you can chain them together in order to display longer strings of digits. They have also added mounting holes to the boards so you can mount them on standoffs.
