TM1637 4 Digital 7 Segment Tube Module for Arduino

TM1637 Arduino Display Module Description The module is a 12-foot clock with 4 points of positive digital (0.36 inches) TM1637 Arduino Display Module 7 Segment 4 Digit in Pakistan display module driver IC TM1637, only two signal lines can make SCM four 8-segment LED. Module features are as follows: Display of male red for the four digital tube Adjustable digital tube 8 gray Level control interface for 5V or 3.3V 4 M2 screws positioning holes for easy installation 4 digital display interface module as shown below: Control Interface: A total of four pins (GND, VCC, DIO, CLK), GND to ground, VCC is the power supply, DIO of data input and output pin, CLK is the clock signal pin; Digital tube: 4 common anode score points with 0.36 inches LED, red highlights; Positioning holes: 4 M2 screws positioning hole diameter is 2.2mm, the positioning of the module is easy to install, to achieve inter-module combination. TM1637 Arduino Display Module inputs: TM1637 LED Display Module 7 Segment 4 Bits Digital Tube with 0.36 Inch Clock Display for Arduino Raspberry PI 3.3V/5V Display Function : Graphics Tube Chip Color : Red Usage : Indoor Model Number : TM1637/en.wikipedia.org is customized ? : Yes 4 digital Module : LED module Seven-segment displays may use a liquid crystal display (LCD), a light-emitting diode (LED) for each segment, an electrochromic display, or other light-generating or controlling techniques such as cold cathode gas discharge (Pentaplex), vacuum fluorescent (VFD), incandescent filaments (Sumiton), and others. For gasoline price totems and other large signs, vane displays made up of electromagnetically flipped light-reflecting segments (or “vanes”) are still commonly used. A precursor to the 7-segment display in the 1950s through the 1970s was the cold-cathode, neon-lamp-like nixie tube. Starting in 1970, RCA sold a display device known as the Sumiton that use incandescent filaments arrange into a seven-segment display. In USSR, the first electronic calculator “Vega”, which was produce from 1964, contains 20 decimal digits with seven-segment electroluminescent display.
