4-digit LED display module, red highlights, with adjustable LED brightness and clock point, can display decimals, letters, etc..
The driver IC is TM1637, compatible with Arduino..
The digital display tube can be controlled with only two signal lines, simple and easy to use..
Control interface: a total of 4 pins (GND, VCC, DIO, CLK), GND to ground, VCC for the power supply, DIO for the data input and output pins, CLK for the clock signal pin..
4 M2 screw holes, easy to install, locate and combine modules..

This Ir transmitter sensor module is directly launched by a single tube.
It requires waveform modulation through the program.
Pin Definitions: (1) Output (2) Vcc (3) GND.
Attention: The white smudge is not corrosion damage, it's flux, can wipe it off with a rag, does not affect the use of the module.
Widely used for infrared communication, infrared remote control, apply to a variety of platforms including Arduino/51/AVR/ARM.
