TM1637 7-Segment Display Module
Most displays require a lot of connection pins. That is quite complex and does not leave much space for other sensors or modules to connect with the Arduino Board. The TM1637 display module only uses four pins. Two pins are required for the power connections and the other two are used to control display.
A 7-segment display contain individually addressable LEDs. The segments are labeled from A to G. To be able to set the LEDs you should know which segment corresponds to which letter. The image shows how the display segments are labeled.
