The module is a 12-pin 4-digit common anode digital tube (0.36 inch) display module with clock dots.
The driver chip is TM1637. Only 2 signal lines are required to enable the single-chip microcomputer to control a 4-digit 8-segment digital tube.
1. The display device is a 4-digit common anode red-digit digital tube, which can be used to display decimals, letters, etc.
2. The digital tube 8 grayscale adjustabley.
3. The control interface level can be 5V or 3.3V .
4. 4 * M2 screw positioning holes for easy installation.
4 common anode score points
GND to ground
VCC for the power supply
DIO for the data input and output pins
CLK for the clock signal pin
Power supply voltage: DC 3.3V-5V
Module current: 30-80MA (when 5V power supply)
