TM1637 4-digit 7-segment LED display module
TM1637 4-digit 7-segment LED display module with 2-wire interface, adjustable brightness, and Arduino compatibility—ideal for clocks and counters.
The TM1637 4-Digit 7-Segment LED Display Module is a compact and easy-to-use display solution for showing numeric data in embedded and microcontroller-based projects. Powered by the TM1637 display driver IC, it requires only two control pins (CLK and DIO), making it ideal for projects with limited I/O pins.
This module features a bright 4-digit 7-segment LED display with a built-in colon, suitable for displaying time, counters, sensor values, voltages, and timers. It supports adjustable brightness levels and delivers stable performance with low power consumption.
Fully compatible with popular platforms such as Arduino, ESP32, ESP8266, Raspberry Pi, and STM32, the TM1637 module is widely used in digital clocks, timers, counters, DIY electronics, and educational projects.
