10pcs Key Display 8-Bit Digital LED Tube 8-Bit TM1638 Module

Descriptions:Includes the following resources:1,8 keys,2,8 a LED3,8-bit digital control, common cathode LED digital tube;4, can be directly connected to the microcontroller, such as STC;5, there is provided ardiuno driver;The module is used in chip TM1638, a collection of these three common microcontroller peripheral circuits, the biggest feature is only occupied three microcontroller IO port to drive, do not need to scan display and keypad scanning microcontroller intervention, just read the relevant register send display data or test button, save MCU resources. Buy This module provides examples of procedures.Imagine, we usually use an external microcontroller 8 LED, 8 digital tube, eight buttons that will occupy the number of IO ports, far more than three IO port it, but with this module can be achieved. The practical applications, key sensitive display good results.Wiring methods:VCC GND connected to 5V power supply, STB CLK DIO connected microcontroller IO port. Package Included:Key digital LED display module X10
