Clearly Display Numbers

Display numeric data on this simple screen. 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.

  • Control display in one of three ways: Serial TTL communication, SPI serial communication, or I2C serial
  • Program it for stand-alone operation--it comes pre-loaded with the Arduino bootloader
  • Includes an FTDI header on board and a hardware profile for the Arduino IDE to make it even easier to program

We’ve made some layout changes to this design as well which will make it easier to incorporate these into your project. We’ve 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. We’ve also added mounting holes to the boards so you can mount them on standoffs (no more hot glue!)

Dimensions: 41mm x 23mm (1.6in x 0.9in)
