TM1637 display module for LED clock build - 4-digit 7-segment 3-5 V

Product description: TM1637 display module

4-digit LED display with built-in TM1637 driver greatly simplifies controlling a 7-segment screen. Thanks to the integrated chip, full control of the module requires only four pins: CLK, DIO, VCC and GND. This allows convenient display of various information such as current time, speed, pressure, and many other parameters. The module is fully compatible with popular microcontroller platforms: for Arduino, for ESP8266, for ESP32, and for Raspberry Pi.
