0.56-inch 1-digit 7-segment common anode LED display is an electronic component used to display decimal numerals (0-9) and some letters. It consists of seven LED segments (labeled A to G) arranged to form a figure-8 pattern, plus an optional decimal point (DP), making a total of eight segments. In a common anode configuration, all the anodes of the LED segments are connected together to a positive voltage (e.g., Vcc), and individual segments are illuminated by applying a LOW signal (ground) to the corresponding cathode through a current-limiting resistor.

Specifications :

• Size: 0.56 inches (digit height).
• Configuration: Common anode (all anodes tied to a single pin, typically connected to +Vcc).
• Pin Count: Usually 10 pins (2 for common anode, 7 for segments A-G, 1 for decimal point).
• Voltage: Forward voltage typically around 1.8V–3.5V, depending on color (e.g., red: ~2.0V, blue: ~3.5V).
• Current: Each segment typically draws 10–20 mA when lit. A current-limiting resistor (e.g., 220Ω for 5V supply) is required per segment to prevent damage.
• Colors: Available in red, blue, green, white, yellow, etc. Red is most common.
• Applications: Used in digital clocks, counters, meters, and basic displays.
