LN8 8-bit Active Low Blue LED Display Module

LN8 8-bit Active Low Blue LED Display Module

The LN8 8-bit Active Low Blue LED Display Module is a compact, breadboard-friendly indicator board featuring eight blue LEDs arranged in a single row. Designed for ease of prototyping, each LED is active-LOW enabled—meaning a LOW logic level turns an LED ON—and the module is TTL-compatible with a wide supply voltage range from 3 V to 12 V. Its common-anode configuration consolidates all LED positive terminals, simplifying wiring via a pin header. The module seamlessly integrates with microcontroller boards such as Eta32 and Betamini.

Features

• 8-bit blue LED display module.
• Active LOW input enables LEDs.
• Common anode configuration with single positive pin header.
• TTL logic compatible.
• Wide input voltage range of 3V–12V.
• Suitable for breadboard prototyping and testing.
• Compatible with microcontroller kits such as Eta32 and Betamini.

PINOUT

Notes:

• Each LED cathode line includes a 1K series resistor on the PCB as shown in the schematic; no additional series resistors are required for typical TTL logic-level sinking, but confirm desired LED current before applying a higher VCC.
• Active-LOW operation: the microcontroller or driver must sink current to turn LEDs ON (drive the LED pin LOW). When the pin is HIGH or high-impedance, the LED will be OFF.
• Verify header orientation physically on your module before wiring — the table lists the PCB labels exactly as shown in the supplied schematic image.
