Adafruit 1.2" 4-Digit 7-Segment Display w/I2C Backpack - Green

What's more vibrant than a standalone LED? A multitude of them! A 4-digit 7-segment display turns simple numeric representation into a bright and engaging visual. Traditional LED matrices are multiplexed, requiring 14 pins for full control. Driver chips like the MAX7219 can manage these matrices, but they involve significant setup and space.Adafruit's LED matrix backpacks simplify this complexity. Available for various 8x8 and 7-segment displays, these backpacks optimally integrate with our stocked displays, easing the task of creating eye-catching numeric displays. The backpacks feature a built-in clock for multiplexing and constant-current drivers, ensuring ultra-bright and consistent color output.With a straightforward I2C interface, enjoy features such as 1/16 step display dimming and the flexibility to connect up to eight 7-segment displays on a single I2C bus. This kit comprises a fully tested LED backpack, ultra-bright 4-digit 1.2" tall green seven-segment display, and a 5-pin header.A minimal soldering effort is needed, taking approximately five minutes, with complete guidance provided in our comprehensive tutorial. Additionally, we offer libraries compatible with Arduino and Raspberry Pi for quick implementation. This product is a seamless solution for anyone seeking simplified control over LED matrix displays.
