A four-digit 0.54-inch blue alphanumeric LED display with an I2C backpack. Each digit has 14 segments, allowing it to display letters, numbers, and basic symbols. The bright blue LEDs on a black surface are readable from up to 7 metres (23 feet) away.

The I2C backpack simplifies wiring to just two data pins. Multiple backpacks can be daisy-chained on the same I2C bus — solder the address jumpers on the back to set up to 8 unique addresses. A small amount of soldering is required to attach the displays to the backpack (about 5 minutes).
