TM1637 4‑Digit 7‑Segment Display Module

The TM1637 4 Bits Dig­i­tal Tube LED Dis­play Mod­ule is an afford­able solu­tion for dis­play­ing the out­put data of your Arduino project. Though the data dis­played is restrict­ed by num­bers still it allows users to dis­play some char­ac­ters too like A, B, C etc.This 7 seg­ment LED Dis­play has 4 dig­its which are con­trolled by TM1637 Dri­ver Chip. It requires only two con­nec­tions to con­trol this TM1637 4 Bits Dig­i­tal Tube LED Dis­play Mod­ule. Also thanks to the I2C Bus you can con­trol it using only 2 wires, leav­ing more pins avail­able on your Micro­Con­troller to con­nect oth­er things.The mod­ule is a 12-foot clock with four com­mon anode tube (0.36 inch) dis­play mod­ule for dri­ver IC TM1637, only two sig­nal lines can make the MCU con­trol four 7‑segment dig­i­tal tubes.There are sev­er­al mod­ules using this TM1637 chip to form a 4 dig­it numer­i­cal dis­play mod­ule. TM1637 has also key­board input capa­bil­i­ty but is not used in this mod­ule.Pinout Description :LED Dis­play mod­ule to ArduinoGND    –    GND Vcc       –     5V DIO     –      D2 CLK     –     D3Features :Ease to use.Ease of mul­ti­plex­ing.Can use as a 4 dig­it dis­play unit.Can use as a clock dis­play.DIY clock project.4 dig­it dis­play unit.Electrical/Electronic projects.The counter project using 7 seg­ment dis­play.4 M2 screws posi­tion­ing holes for easy instal­la­tion
