Product description: 4-digit 7-segment display module 0.56 '' Backpack - blue I2C - STEMMA QT / Qwiic - Adafruit 881
Adafruit Backpack module with a 7-segment display consisting of 4 digits with dots. The total diagonal of the display is 0.56 " , the module digits have blue backlight with the possibility of dimming with a resolution of 1/16 step. Thanks to the built-in matrix controller of the MAX7219 type, there is no need to connect a large number of wires, the whole is controlled via the I2C interface. The module is additionally equipped with 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. into the plate.
The product is compatible with Arduino and Raspberry Pi
The manufacturer has prepared a user guide that presents connection diagrams and code examples in Arduino and CircuitPython.
Backpack board with HT16K33 LED driver for segment display.Pins of the 7-segment display module
The module communicates with the main board via the I2C interface, on the board you can also find 2 Qwiic / STEMMA QT connectors for quick connection with modules with the same connector. The supply voltage is 3 V or 5 V.
- VCC - supply voltage 3 V / 5 V
- GND - the ground of the system
- SDA - data line of the I2C interface
