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.
