The TM1638 Button Digital LED Display Module is used in chip TM1638, a collection of these three common MCU peripheral circuit, the biggest feature just takes three microcontroller IO port to drive, do not need to scan display and key scanning microcontroller intervention, only need to read the relevant register send display data or test button, save MCU resources.

We usually use an external microcontroller 8 LED, 8 digital tubes, eight keys which will occupy the number of 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. Wiring: VCC GND connected to 5V power supply, STB CLK DIO connected microcontroller IO port. The module comes with 8 buttons, 8 LED, 8 digital tube, common cathode LED digital tube, such as STC microcontroller can be directly connected

How to connect:
VCC GND 5V power supply, STB CLK DIO MCU I/O port. This module for the chip TM1638, set 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 need to register to display data related to reading and writing or testing buttons, save MCU resources.
