TM1637 4-Digit 7-Segment Display Module

TM1637 4-Digit 7-Segment Display Module

The driver supports many functions including on/off and brightness control of the LEDs as well as accessing each of the digits. Once the display is updated by the MCU, the driver takes care of all the work of keeping the display refreshed, so it removes that overhead from the MCU so it can be off doing other things.

These modules communicate via a 2-wire bus, so they only require 2 data pins plus power and ground.  The bus is specific to this device but there are libraries available such as the TM1637.h library for Arduino that hides all the dirty details and makes communicating with the display straightforward.

The display has a center colon commonly used for clock applications, but the display also works fine for some other numeric or hex display purposes.
