TM1638 Button Digital LED Display Module

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

Features:

1. Use TM1638 digital tube drive chip to drive a common cathode LED digital tube.
2. Can be extended to 3 * 8 buttons, led digital tube and can be controlled separately.
3. Support 8 brightness control, led digital tube and use the same brightness.
4. Support cascading up to 6 of the same module.
5. Wiring: VCC GND connected the 5V power supply, STB CLK DIO connected microcontroller IO port.
6. 8 LED, 8-bit digital tube and 8 buttons, common cathode LED digital tube, such as STC microcontroller can be directly connected.

Package Includes:

1 x TM1638 Button Digital LED Display Module
