The TM1637 4-Digit 7-Segment LED Display Module is an affordable solution for displaying output data from your Arduino project. While primarily designed for numeric output, it also supports limited character display (e.g., A, B, C).
This module contains four 7-segment digits driven by the TM1637 driver chip. It requires only two connections for communication, thanks to the efficient use of the I2C-like protocol, freeing up pins on your microcontroller for other uses.
It features a compact 12-pin clock-style layout using a 0.36-inch 4-digit common anode tube, controlled by the TM1637 IC. Only two signal lines are needed to control the four 7-segment displays.
