TM1637 Module Hardware Overview

At the heart of the module is an inexpensive serial LED driver from Titan MicroElectronics – TM1637.

The TM1637 supports many functions – including ON/OFF and brightness control of the LEDs as well as accessing each of the segments. It also allows you to adjust the brightness of the LEDs at software level.

And another good thing is that once the display is updated by the microcontroller, the TM1637 then takes care of all the work of refreshing the display. Thereby removing the overhead from the microcontroller, which can be off doing other important things.

The TM1637 module includes four 0.36 segment 7-segment displays to display sensor data or temperature. In addition to the four 7-segments, the module has a Great scott ‘colon’ at the center which makes it very easy to create clock or time-based projects.

The TM1637 module operates on a supply voltage of 3.3 to 5 volts and communicates via a two-wire bus, so it only requires two data pins plus VCC and ground. The bus is specific to this device, but there are libraries available for Arduino that hide the complexities and make it easier to communicate with the display.

TM1637 Module Pinout

There is a 4-pin right angle male header on the module for making connections.

CLK is a clock input pin. Connect to any digital pin on Arduino.

DIO is a Data I/O pin. Connect to any digital pin on Arduino.

VCC pin supplies power to the module. Connect it to the 3.3V to 5V power supply.

GND is a ground pin.
To talk to the TM1637 chip you’ll need to use a library. Avishay Orpaz has written an excellent library for TM1637 displays, the TM1637Display library. This library has several built-in functions that make controlling the display fairly easy. You just specify which number to display and it is handled for you
