The TM1637 4 Bits Digital Tube LED Display Module is an affordable solution for displaying the output data of your Arduino project. Though the data displayed is restricted by numbers still it allows users to display some characters too like A, B, C etc. Use this module to build a digital counter, clock, squid game red light green light project or ultrasonic range finder.

The Common Anode 4-Digit Tube Display Module with the TM1637 driver chip simplifies digital display projects, requiring just two connections for controlling four 8-segment displays. Featuring red LEDs with a common anode, it operates with a power supply of 3.3V or 5V. Driven by the IC TM1637, this module is compatible with Arduino and other devices, enabling MCU control with only two signal lines. Its versatility extends to adjustable 8-segment digital tube configurations. Documentation, including libraries and tutorials, is available on GitHub and YouTube. The package includes one 4-Bit 8-Segment Digital Tube LED Display Module with Clock functionality, tailored for Arduino projects.
