0.56inch 4-Bit 7 Segment LED Display Module with Clock HT16K33 Driver Chip for Digital Clock Countdown Timer A

0.56inch 4-Bit 7 Segment LED Display Module with Clock HT16K33 Driver Chip for Digital Clock Countdown Timer A Popis

Classic 4-Digit Display: Features a high-brightness 0.56-inch 7-segment display with a decimal point, designed for clear numerical visibility. It includes a built-in colon separator, making it ideal for electronic clocks or timers.
Simple I2C Control: Powered by the onboard HT16K33 driver chip, the display is controlled via I2C commands using only two I/O pins, greatly simplifying both programming and hardware connections.
Constant-Current Drive for Uniform Brightness: The driver chip utilizes a constant-current source to power the LEDs, ensuring consistent color and brightness across all digits at any intensity level.
Plug-and-: Integrated with STEMMA QT / Qwiic standard connectors for quick, solder-free connections.
Flexible Cascading: Supports I2C address adjustment (ranging from 0x70 to 0x77) via onboard address jumpers, allowing to eight modules to be cascaded a single I2C bus.
