The HS310561K is a compact, 0.56-inch 3-digit seven-segment LED display module configured in a Common Cathode (CC) layout. Designed with bright red LED segments set against a high-contrast black face, it offers crisp alphanumeric legibility and wide viewing angles. It utilizes a multiplexed 12-pin dual-inline package (DIP) to minimize microcontroller pin requirements, operating efficiently at a low forward voltage of 1.8V to 2.2V (10–20mA per segment). This reliable module is perfectly suited for breadboard prototyping and seamless integration into digital counters, clocks, voltmeters, and custom DIY embedded hardware projects.
Are you looking to integrate this module into a new design? I can help you map out the exact 12-pin layout or write a basic Arduino control code to get the display running without any screen flicker.

product overview
The HS310561K is a high-efficiency, 0.56-inch, 3-digit seven-segment LED display module engineered for reliable alphanumeric readouts in low-light and high-contrast environments. Featuring a Common Cathode (CC) configuration, this space-saving display combines twenty-four distinct light-emitting segments (3 digits × 7 body segments + 3 decimal points) into a unified, multiplexed package utilizing a standard 12-pin dual-inline layout. Designed with bright red GaAsP/GaP semiconductor dies embedded against a deep black face substrate with white structural masking, it delivers crisp visibility, exceptional viewing angles, and a professional aesthetic for industrial and hobbyist projects alike.

Key Features
-
- High-Contrast Optical Build: Matte black surface layout dramatically cuts down ambient reflection, making the illuminated red segments stand out sharply.
- Efficient Multiplexed Matrix: The internal architecture interconnects corresponding segment anodes across all three digits, reducing the hardware layout footprint from 24 individual trace leads down to just 12 pins.
- Universal Microcontroller Compatibility: Seamlessly interfaces with 3.3V and 5V logic platforms including Arduino, ESP32, Raspberry Pi Pico, PIC, and STM32 using basic shift registers (e.g., 74HC595) or dedicated display drivers (e.g., MAX7219).
- Robust Mechanical Design: Standard pin-spacing structure allows for immediate drop-in integration onto prototyping breadboards, stripboards, or custom production PCBs.
