The TM1637 4 digit 7 Segment LED Display is a low-cost solution for displaying Arduino project output data. Though the data displayed is limited to numbers, users can also display characters such as A, B, C, and so on. The TM1637 Driver Chip controls the 4 digits on this 7 segment display. This TM1637 4 Bits Digital Tube LED Display Module can be controlled with just two wires.
Also, thanks to the I2C Bus, you can control it with only two wires, freeing up more pins on your Microcontroller for other purposes. The module is a 12-foot clock with four common anode tube (0.36 inch) display module for driver IC TM1637, with only two signal lines allowing the MCU to control four 7-segment digital tubes.
