Detail about 4 Bits TM1637 LED Digital Clock Tube Display Module
TM1637 is a chip for driving 7-segment displays. There are several modules using this chip to form a 4 digit numerical display module. TM1637 has also keyboard input capability, but is not used in this module. The Arduino Interface library is also available at github. The module is a 12-foot clock with 4 points of positive digital (0.36 inches) display module driver IC TM1637, only two signal lines can make SCM four 8-segment LED.
