Description
The 4-Bit TM1637 Red LED Display Module is a versatile numeric display module that combines four 7-segment red LEDs with an integrated TM1637 driver IC for easy communication and control. It is widely used for displaying time, counters, scores, and numerical data in DIY electronics, IoT projects, and embedded systems.
With its TM1637 driver, the module uses only two control pins (CLK and DIO), significantly simplifying connections to microcontrollers such as Arduino, ESP32, STM32, and Raspberry Pi. It also supports adjustable brightness and can function as a digital clock, making it a convenient solution for a wide range of applications.
Features
