1-Digit 7-Segment Common Cathode LED

The 1-Digit 7-Segment Common Cathode LED is a compact display module used to show numerical values and some limited characters. It consists of 7 individual LED segments arranged in a specific pattern along with a decimal point. In the common cathode configuration, all LED cathodes are connected together, making it easy to interface with microcontrollers like Arduino, ESP32, and Raspberry Pi using direct GPIO control or driver ICs.

Features:

• Common Cathode Configuration: All cathodes are internally connected to ground
• Clear Numeric Display: Displays digits from 0 to 9
• Decimal Point Included: Supports decimal value indication
• Easy Interface: Can be driven directly from microcontroller pins or through drivers
• Low Power Consumption: Efficient LED-based display
• Compact Size: Suitable for embedded and compact projects
• Wide Compatibility: Works with Arduino, ESP boards, and other microcontrollers
• Durable and Reliable: Long lifespan compared to traditional displays

Specifications:

• Display Type: 1-Digit 7-Segment LED
• Configuration: Common Cathode
• Forward Voltage: Approximately 1.8V – 2.2V per segment
• Forward Current: Typically 10mA – 20mA per segment
• Number of Segments: 7 segments + 1 decimal point
• Operating Voltage: Depends on segment current limiting (usually 3V – 5V systems with resistors)
• Interface: Direct GPIO or via driver IC (e.g., shift register or decoder)
• Dimensions: Compact standard 7-segment display size
