TTM1638 Module Switch Screen AVR Arduino 8-Bit Digital LED Card

TM1638 Module Key Screen

8-digit 7-segment screen module (HCMODU0095),It uses TM6138, which allows full control of the screen using only 3 digital pins on the arduino and other microprocessors. In addition to the 7-segment screens, there are 8 3mm Led and 8 butons that can be controlled separately. It is also checked with TM6138 IC, and it can be controlled without requiring an extra digital pin. With standard 5-pin header connections, it provides an easy interface to your microcontroller.

The module has a special library (HCTI6138) for its easy use with Arduino. The library will provide complete control over the 7-segment screen (which will provide the ability to show alfanumeric text), 8 LED and read the status of the keypad. It also has the ability to control multiple modules from an Arduino.

TM1638 Module Technical Properties

The following resources are included:

1. 8 key

2. 8 LED joint cathode

3. 8 digital tube joint cathode

Use common cathode LED digital tube driver TM1638 digital tube driver chip.

How to connect:

VCC GND 5 V power supply, STB CLK DIO MCU I/O port

For chip TM1638, this module, set up the three types of single-chip microcomputer common perimeter circuit above. The largest feature can only be microcontroller three IO gagged, the scan screen and key scanning do not need microcontroller intervention, you only need to register to view the data related to read and write or test buttons. Save the MCU resources. Purchasing the module provides a sample program.

Cabling methods:

VCC GND attached 5 V source, STB CLK DIO connected micro IO portu.
