LP8 8-bit Active High Red LED Display Module

From the shop's description

LP8 8-bit Active High Red LED Display Module The LP8 8-bit Active High 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-HIGH enabled—meaning a HIGH 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-cathode configuration consolidates all LED negative terminals, simplifying wiring via a pin header. The module seamlessly integrates with microcontroller boards such as Eta32 and Betamini. Features 8-bit red LED display module. Active HIGH input enables LEDs. Common cathode configuration with single negative 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.

Active-HIGH operation: the microcontroller or driver must provide current to turn LEDs ON (drive the LED pin HIGH). When the pin is LOW or low-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.
