3.3-5V 8-Bit LED Module - Red

The 3.3-5V 8-Bit LED Module (Red) is a compact indicator module featuring 8 LEDs arranged side-by-side, designed for visually monitoring the status of digital outputs. It simplifies the simultaneous display of the status of 8 different digital lines in microcontroller projects.

Compatible with 3.3V and 5V logic levels, this module can be used in electronic applications involving microcontrollers or development boards such as Arduino, ESP32, ESP8266, STM32, and Raspberry Pi. Having 8 LEDs on a single compact module streamlines prototyping and testing processes by eliminating the need to wire individual LEDs and resistors for each output.

The module utilizes a common-positive connection configuration. The COMM/VCC pin connects to the positive supply line, while the 8 individual LED pins connect to control signals. An LED illuminates when its corresponding input is pulled to a logic LOW level and turns off when the input is at a logic HIGH level.

This configuration allows for easy monitoring of microcontroller port output states.
