TM1637 4 Bits Digital Tube LED Display Module With Clock Display for Arduino

The TM1637 4 Bits Digital Tube LED Display Module presents an economical solution for showcasing Arduino project output data. While primarily limited to numeric displays, it also allows for the presentation of characters such as A, B, C, and more.

This module features a 7-segment LED Display comprising four digits, each controlled by the TM1637 Driver Chip. Remarkably, it necessitates only two connections to command the display. Leveraging the I2C Bus, you can effortlessly manage it with just two wires, freeing up additional pins on your Microcontroller for other peripherals.

Equipped with a 12-foot clock and four common anode tube (0.36 inch) display, this module interfaces with the driver IC TM1637, enabling the MCU to govern four 7-segment digital tubes via a mere two signal lines.

Numerous modules utilize the TM1637 chip to configure a 4-digit numerical display. While TM1637 features keyboard input capabilities, they remain untapped in this module’s design.
