LN8 8-bit Active Low Red LED Display Module
The LN8 8-bit Active Low Red LED Display Module is a compact, breadboard-friendly indicator board featuring eight red 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.

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.
