DIYables 4 Digit 7 Segment Display Module TM1637 0.56 Inch Red for Arduino for Arduino, ESP32, ESP8266, Raspberry Pi

Quick Overview

The DIYables TM1637 4 Digit 7 Segment Display Module puts a bright red numeric readout on your project without eating up your board pins. Each of the four 0.56 inch digits is driven by the onboard TM1637 controller, so the whole display needs only two signal lines, CLK for the clock signal and DIO for data, alongside VCC and GND. That leaves the rest of your GPIO free for sensors, buttons, and everything else in the build.

A colon segment sits between the second and third digits and is under software control, which makes hh:mm and mm:ss formats straightforward for clocks, timers, and stopwatches. Brightness is adjustable across 8 gray scale levels, so the same module stays readable on a workbench and dims down for a bedside clock. The control interface runs at 5V and the four pin header is ready for jumper wires, so there is no soldering or complicated wiring to work through.

Ideal for digital clocks, countdown and interval timers, stopwatches, scoreboards, counters, temperature and voltage readouts, and any project that needs a clear numeric display. C/C++ and MicroPython libraries plus step by step tutorials are available for Arduino, ESP32, ESP8266, and Raspberry Pi Pico.

Key Features

0.56 Inch Red Digits — Four large 0.56 inch red seven segment digits stay legible from across a room
TM1637 Driver IC — Onboard TM1637 controller handles all segment multiplexing so your code only sends the value to show
Two Wire Interface — Only CLK and DIO are needed for data, leaving the rest of your GPIO pins free for other parts
Colon Separator — Software controlled colon between the second and third digits for hh:mm and mm:ss time formats
8 Level Brightness — Eight gray scale steps let you dim or brighten the display from code to suit the room
5V Control Interface — Control interface electrical level is 5V, matching standard microcontroller logic
Plug and Play Wiring — Four pin header connects with jumper wires, no soldering or complicated wiring process
Stable Structure — Digits and driver are mounted on a single rigid PCB for a solid, repeatable build
Library Support — C/C++ and MicroPython libraries are provided for a quick start
Tutorial Support — Step by step tutorials for Arduino, ESP32, ESP8266, and Raspberry Pi Pico
2 Pack Value Set — Two modules for dual display builds, spares, or classroom use
Versatile Applications — Clocks, countdown timers, stopwatches, counters, scoreboards, and sensor readouts
