Product Description
TM1638 Digital 8Bit LED Tube 8 Keys Display Module for AVR Arduino ARM
Features
It includes the following resources:
1,8 keys,
2,8 a LED,
3,8 digit LED
The module is used in chip TM1638, a collection of these three common MCU peripheral circuit, the biggest feature is to simply occupy three microcontroller IO port to drive, do not need to scan display and keypad scanning microcontroller intervention, only to send the relevant register read display data or test button, save MCU resources. The module provides examples of purchasing procedures.
Imagine, we usually use an external microcontroller 8 LED, 8 digital tube, eight buttons that take up much needed IO ports, far more than three IO mouth it, but with this module can be achieved. The practical application of key sensitive display good results.
Connection methods:
VCC GND connected to 5V power supply, STB CLK DIO connected microcontroller IO port.
