Designed to make a 7 segment display much easier to control by adding a microcontroller, allowing full control using just a few serial lines. Incorporates a 4 digit, white alpha-numeric display with TTL, SPI or I2C Serial Interface.The integrated ATMega328 microcontroller allows you to control each segment individuallyDisplay numbers, most letters and a few special characters; with individual control of decimal points, apostrophe and colonControl the display in three ways: with Serial TTL, SPI Serial or I2C Serial communicationMicrocontroller is preloaded with the Arduino bootloader, allowing for standalone operationOnboard FTDI header for easier programmingMounting holes for permanent installationSelectable baud rate and brightnessBaud rate and brightness values retained in non-volatile memoryDimensions: 41x23mmContentsDisplay board only
