This 0.56-inch 4-bit 7-segment display module comes with a clock function. 2. This 7-segment display matrix is multiplexed, and to control all 7-segment LEDs, you need 14 pins. 3. This module can easily add a 4-digit digital display with a decimal point, which can be used to create the "second colon point" of a clock. 4. Using a matrix driver chip (HT16K33) perform multiplexing . You need to send an to the chip, telling it which LEDs to light up, and it handle it . 5. As it only uses for control, it can be used with any development board and can share pins with other sensors or displays. Display screen: 0.56 inches The board/chip uses an 7-bit address between 0x70-0x77, which can be by jumper; 4-digit 7-segment LED matrix display screen, ultra bright 4-digit 0.56-inch high blue 7-segment display screen; Paired with pins, the matrix can be fixed to the development board, which is very easy to operate and only takes about 5 minutes!
