SparkFun 7-Segment Serial Display - Blue
We have ✅ 2 available of the SF-COM-11442 in our Sydney warehouse. An extra 28 units available with a short lead time.
The SparkFun 7-Segment Serial Display combines a 4-digit 7-segment LED display with an ATmega328 microcontroller, allowing you to control every segment using just a few serial lines. It supports three communication interfaces — Serial TTL, SPI, and I²C — making it easy to integrate into a wide range of projects.
The on-board ATmega328 comes pre-loaded with the Arduino bootloader, so the display can also be programmed for stand-alone operation via the FTDI header. Power and I²C pins are positioned on the sides of the board for daisy-chaining multiple displays, and mounting holes are included for secure installation.
