8-Bit LED 8-Bit Digital Tube 8 KeyS TM1638 Display module for AVR Arduino ARM

Features:
100% brand new and high quality
8bits, 8keys,8LEDs,8digital tubes，Common cathode LED digital tube
With TM1638 Chip, this module gather more than 3 common SCM Peripheral circuits.
The advantage is that only three IO ports will be occupied when it drives.
SCM doesn't need to work for scaning display and key scaning.
It only need to read the relevant register to send display data or test button so it save MCU resources effectively.
Keys are sensitive and display effectively.
How to connect: VCC GND 5V power supply, STB CLK DIO SCM IO port


Specification:
Weight: 28g
Color: as the picture show
Material: glass fiber reinforced plastic, PBT shell, PA blades


Package Included:
1xLED Display Module
5xDupont Lne Connectors

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. Buy the module provides an example program.

 

Wiring methods :

VCC GND connected 5V supply, STB CLK DIO connected microcontroller IO port
