Includes the following resources:

8 keys
8 LED common cathode
8 digital tube common cathode
Uses TM1638 digital tube drive chip to drive common cathode LED digital tube

How to connect:

VCC GND 5V power supply, STB CLK DIO MCU I/O port
This module for the chip TM1638, sets the above three kinds of single chip microcomputer common peripheral circuit, the biggest characteristic is to simply take microcontroller three IO mouth can drive, scanning display and key scan don't need microcontroller intervention, only needs to register to display data related to reading and writing or testing buttons, save MCU resources
Buying the module provides an example program
