SPECIFICATIONS

TM1637 is a specialized circuit for LED (Light Emitting Diode Display) driver control with keyboard scanning interface. It integrates MCU+digital interface, data latch, LED high-voltage driver, keyboard scanning and other circuits internally. Can be applied to display screen drivers for induction cookers, microwave ovens, and small household appliances.

The module features are as follows:

Display device is 4-digit yang red digital tube

Digital tube 8-level grayscale adjustable

Control interface level can be 5V or 3.3V

4 M2 screw positioning holes for easy installation

Control interfaceA total of 4 pins (GND, VCC, DIO, CLK), GND is ground, VCC is the power supply, DIO is the data input and output pin, CLK is the clock signal pin;

Digital Tube: 4-digit common anode with a 0.36-inch digital tube with a score point, highlighted in red;

Positioning hole: 4 M2 screw positioning holes, the hole diameter is 2.2mm, which makes the module easy to install and position, and realize the module combination;

Overview of the library routines:

1. ClockDisplay: Use the timer 1 of the MCU on the motherboard to time and let the 4-digit display display.

2. NumberFlow: 0~9, A, b, C, d, E, F and other 16 characters flow from right to left.

3. StopWatch: Use the timer 1 of the MCU on the motherboard to time, and use the button to realize the stopwatch function.
