TM1637 4-Digit 7-Segment Display Module


A 4-digit 7-segment display is a must-have for any project involving a clock, timer, or counter, but connecting a bare display to an Arduino requires a dozen-or-so pins, leaving little room for other sensors and modules.

This display module uses tm1637 IC controller. It requires only four connections in total – two for power and two for controlling the display.

Features of TM1637 4-Digit 7-Segment Display Module:

  • TM1637 controller makes it controllable using serial protocol with only four pins.
  • Bright red display for 4 characters with 7 segments and colon.
  • Level control interface for 5 V or 3.3 V
  • 4mm screws holes for easy installation
