LN8 8-bit Active Low Blue LED Display Module

Description

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 PIN Function / Notes 7 Cathode of LED L7 6 Cathode of LED L6 5 Cathode of LED L5, 4 Cathode of LED L4 3 Cathode of LED L3 2 Cathode of LED L2 1 Cathode of LED L1 0 Cathode of LED L0 V Common anode (VCC). All LED anodes are tied together to this net. Connect this pin to the LED supply voltage (typical 3V–12V). Do not exceed the module supply rating. G Not connected / reserved 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.
