A TM1637 4-Digit 7-segment LED display is a type of electronic display used to show information in numerical form. They are often used in electronic devices such as clocks, calculators, and radios.

The TM1637 display is an excellent method to add numerical information to an electronic project. These displays are easy to use and deliver a clear and straightforward way to display numbers. By following a few easy guidelines, anyone can use a TM1637 display to add numerical information to their project.

The module works between 3.3V to 5V with a current consumption of 80mA. We can interface TM1637 with Raspberry Pi Pico or any different microcontroller operating the two data pins. There is a committed MicroPython Library for TM1637 that removes the complexity and drives it more straightforwardly to communicate with the display.

  3. VCC: 3.3V to 5V power supply Pin
  4. GND: Clock Input Pin

Raspberry Pi Pico

raspberry-pi-picoRaspberry Pi Pico is a low-cost, high-performance microcontroller board with flexible digital interfaces. It is developed for makers, teachers, and anyone interested in creating interactive applications that control physical systems. With its low price, small size, and comfort of use, the Raspberry Pi Pico is perfect for anyone who wants to get started with coding and hardware interfacing. Before we used  Raspberry Pi Pico to build many Projects.

How to Connect TM1637 Module With Raspberry Pi Pico

Connect the ground (GND) pin on the TM1637 module to the ground (GND) pin on the pi pico. Then, connect the power (VCC) pin on the TM1637 module to the power (5V) pin on the Pico. Now, connect the data (DIO) pin on the TM1637 module to the GPIO Pin 1 pin on the Pico. Finally, connect the clock (CLK) pin on the TM1637 module to the 0 pin of the Raspberry Pi Pico respectively.
