4 Digit 7-Segment Display Module I2C
Specification
This 7 segment LED Display has 4 digits which are controlled by TM1637 Driver Chip.
It requires only two connections to control this TM1637 4 Bits Digital Tube LED Display Module.
Also thanks to the I2C Bus you can control it using only 2 wires, leaving more pins available on your MicroController to connect other things.
The module is a 12-foot clock with four common anode tube (0.36 inch) display module for driver IC TM1637, only two signal lines can make the MCU control four 7-segment digital tubes.
There are several modules using this TM1637 chip to form a 4 digit numerical display module.
TM1637 has also keyboard input capability but is not used in this module.
TM1637- 4 Digit Display Module
TM1637 4 digit display Module is a 4-pin module for digital display through the combination of four 7-segments.
The module is basically for a digital display of alphanumeric data.
The basic structure of the module is with the combination of four 7-segments and two LEDs.
The LEDs uses as a ratio sign display.
Therefore, the whole LCD comes up with the 12 pins output but TM1637 IC minimizes them to only two pins.
The small number of pins of the module and display of data with 7-segment make it preferable by some developers.
The module is quite popular in most commercial and industrial products.

TM1637 Module Pinout Diagram
The 4 Digit display is popular because of its small numbers of control pins.
In which these 4 pins, two of them are power pin and the rest two pins control the display value on the module.
All pins of the module are
Power Pins
The power pins consist of two pins like all other devices.
The first pin is the power (VCC) input
pin to give the voltages to the module.
The ground (GND) is pin to make the common ground with external devices.
Communication Pins
There are only two communication pins, in which one is a clock pin (CLK) and the second one is a data pin.
The Clock pin helps to keep the clock pulse sync in with module and microcontroller/Arduino.
The data pin helps in sending and receiving data from the microcontroller/Arduino board.
4 Digit Display Module Features
The use of only two pins can control the four combined 7-segments.
The device is compatible with Arduino boards with the use of a single library.
Any alphanumeric value can show on the module from the microcontroller.
The module TM1637 gives the 8 luminance levels which are adjustable through the programming.
The device operates on both 3.3V and 5V.
Applications
The module is commonly available in the power display devices.
In stopwatches and timers, module usage is mostly at the developers’ level.
The module is also available in Payer timing devices at Masjids.
The utility power meter also uses to show the data
