TM1637-4 Digit 7 Segment Display Module

The TM1637 is a 7-segment 4-digit display that can be easily controlled by an Arduino with a few wires. There are 12 pins on a 4-digit, 7-segment LED display. 8 of the pins are for the 8 LEDs on a 7-segment display (A-G and DP) (decimal point). The remaining four pins correspond to the four digits D1-D4. The TM1637 Driver Chip controls the 4 digits on this 7-segment LED Display. This TM1637 4 Bits Digital Tube LED Display Module can be controlled with only two connections. You can also power it with just two wires thanks to the I2C Bus, which frees up more pins on your Micro Controller to attach other stuff.
