TM1637 Red Display Module - 0.36 Inch 4-Digit 7-Segment Clock

This module is a 12-pin clock featuring a 4-digit positive digital display (0.36 inches) driven by the TM1637 IC. It allows control of four 8-segment LEDs using only two signal lines with a single-chip microcontroller (SCM).

Module Characteristics

• The four-digit tube displays in a striking red color.
• The digital tube's brightness can be adjusted across 8 gray levels.
• The level control interface is compatible with both 5V and 3.3V.
• Four M2 screws positioning holes are provided for straightforward installation.
• This is a 4-Digit Display Interface Module.

Control Interface

The interface consists of four pins (GND, VCC, DIO, CLK). GND refers to the ground, VCC is the power supply, DIO is the data input and output pin, and CLK is the clock signal pin.

Digital Tube

The digital tube comprises 4 common anode score points with a 0.36 inches LED, which displays in bright red.

Positioning Holes

The module features four M2 screws positioning holes with a diameter of 2.2mm. This design makes the module easy to install and allows it to be combined seamlessly with other modules.
