4 Bits Tube Led Display Module Four Serial for Arduino 595 Driver

The TM1637 4 Bits Digital Tube LED Display Module is the prominent and perfect device for displaying the output data of your Arduino project. This module is designed as a 12-foot clock point four common anode tube with 0.36inches LED for driver IC.  Although it is restricted to displaying only numbers, it is also capable of displaying certain characters like A, B, C, etc.

This module with 7 segments LED Display supports 4 digits controlled by TM1637 Driver Chip. The heart of this display module is driver IC TM1637. It requires only two signal line connections to control this TM1637 4 Bits Digital Tube LED Display Module. I2C Bus interface control signal line connections, leaving more pins available on your Microcontrollers to connect other things. It provides 4*M2 screws with a positioning hole diameter of 2.2mm. This makes the positioning of the module easier to install, thereby achieving an inter-module combination.

 PIN DESCRIPTION:

• GND: Connected To Ground
• VCC: VCC is the power supply
