SparkFun 7-Segment Serial Display - Blue

The SparkFun 7-Segment Serial Display - Blue is an innovative device that combines a classic 4-digit 7-segment display with an ATMega328 microcontroller. This unique blend allows you to control each segment individually using just a few serial lines. The device is designed to be controlled via Serial TTL communication, SPI serial communication, or I2C serial. The ATMega328 is pre-loaded with the Arduino bootloader, allowing for stand-alone operation.

SparkFun has made some key layout changes to make it easier to integrate this device into your project. The power and I2C pins are now located on the sides of the board, allowing for easy chaining together to display longer strings of digits. Additionally, mounting holes have been added to the boards, allowing for secure mounting on standoffs.

The SparkFun 7-Segment Serial Display - Blue is a 4-digit blue alpha-numeric display with a TTL, SPI or I2C Serial Interface. It can display numbers, most letters, and a few special characters. The device allows for individual control of decimal points, apostrophe, and colon. It also features a selectable baud rate and brightness. Both the baud rate and brightness values are retained in non-volatile memory, and there is individual segment control for each digit. The device measures 41mm x 23mm.

This device is a replacement for COM-09765. It comes with comprehensive documentation including a schematic, Eagle Files, datasheet, hookup guide, Arduino Add-On, and a Github Repo. This wealth of resources makes it easy to understand and use the SparkFun 7-Segment Serial Display - Blue. Whether you're a seasoned professional or a hobbyist, this device offers an engaging and user-friendly way to incorporate a 4-digit 7-segment display into your projects.
