TM1638 Button Digital LED Display Module
A versatile module for driving LED displays and buttons with minimal IO ports.
- Use: TM1638 digital tube drive chip
- Features: 8 Bits Button Digital LED Display Module
- Compatibility: STC microcontroller
Top Features:
- Drive LED displays and buttons with only three microcontroller IO ports
- Supports 8 brightness levels for LED digital tubes
- Can control 8 buttons and LED digital tubes separately
- Allows cascading up to 6 modules for expanded functionality
The TM1638 Button Digital LED Display Module utilizes the TM1638 chip, combining LED display and button control in a resource-efficient manner. By requiring only three IO ports, it simplifies the integration of 8 LED, 8 digital tubes, and 8 buttons, making it ideal for applications where IO port availability is limited.
For wiring, connect VCC and GND to a 5V power supply, while STB, CLK, and DIO should be connected to the microcontroller's IO ports. The module's common cathode LED digital tube design ensures compatibility with STC microcontrollers, enabling seamless integration.
- Power Supply: 5V
- IO Ports: 3 required for operation
- Buttons: 8 included
- LEDs: 8 for visual feedback
- Digital Tubes: 8 for numerical display
- Compatibility: STC microcontroller
