1pcs TM1637 4 Bits Digital LED Display Module For arduino 7 Segment 0.36Inch Clock RED Anode Tube Four Serial Driver Board Pack

1. The module is a 12-pin display module with a 4-point common digital tube (0.36 inch) with a clock point. The driver chip is TM1637. It only needs 2 signal lines to enable the MCU to control the 4-bit 8- Segment digital tube.

   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

   Project	Minimum value	Typical value	Maximum	Unit
   Voltage	3.3	5	5.5	VDC
   Current (@5V)	-	30	80	mA
   Size	42X24X12			Mm
   Weight	8			g

   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.
