Product description: 4-digit 7-segment display module 0.56 '' Backpack - red I2C - STEMMA QT / Qwiic - Adafruit 878
Adafruit Backpack module with a 7-segment display consisting of 4 digits with dots. The display diagonal is 0.56 " , and the module digits are highlighted in red . The whole is controlled by the I2C interface, so there is no need to connect a large number of wires. The module is additionally equipped with two quick-connect connectors - Qwiic / Stemma QT . on the board you can also find jumpers for selecting the I2C address, so you can connect up to eight 7-segment display modules. The module is powered by 5 V or 3 V.
The display module must be self-soldered to the PCB.
4-digit 7-segment display module.
