digital tube.
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.
