The TM1637 module is a low-power, low-cost display module that can be used for many different applications.

The TM1637 module consists of a 4-digit 7-segment display and the TM1637 7-Segment Display Driver IC. The IC supports many functionalities including on-off and brightness control. This IC also has a data queue which means that you can send all the data packets to the IC and the IC will display all the information sequentially, giving headroom to your microcontroller for other tasks.

TM1637 IC Basic Features
TM1637 is a kind of LED (light-emitting diode display) drive controller special circuit with a keyboard scan interface. It is internally integrated with MCU digital interface, data latch, and LED high-pressure drive. Other than that, this IC also has the capability to control the brightness of the display, which means the display can be dimmable if it’s required for the project. This device comes in a DIP and SOIC package and can be used for many different applications like display drives of induction cookers, microwave ovens, and small household electrical appliances.

The TM1637 can also serial upload the display data in the IC, and the IC takes care of refreshing the display, reducing the overhead from the microcontroller. It also features a ‘colon’ that can be used for timer-based projects.

The operating voltage for this module is 3.3V to 5V and it uses a two-wire bus.
