📝 Product Overview

The module consists of a 4-digit numeric display with a center colon, making it perfect for clock or timer applications. On the back, it features the TM1637 driver chip, which handles the multiplexing so your microcontroller doesn't have to. 🕒

⚙️ Technical Specifications

• Driver Chip: TM1637 (Handles all display scanning and driving). 👾
• Display Type: 0.36-inch 4-digit common anode 7-segment display (with center colon). 💡
• Operating Voltage: 3.3V to 5V DC (Compatible with Arduino, ESP32, and Raspberry Pi). ⚡
• Communication: 2-Wire Serial Interface (CLK and DIO). 🔗
• Dimensions: 41.8mm x 23.7mm (as shown in your image). 📏
• Mounting: Features 4 M2 screw holes for easy installation in cases or panels. 🛠️

📌 Pinout Description

The module has a 4-pin header for simple wiring:

• CLK: Clock input pin. ⏱️
• DIO: Data Input/Output pin. 📤
• VCC: Power supply (3.3V - 5V). 🔴
• GND: Ground connection. ⚫

🌟 Key Features

• Adjustable Brightness: The driver chip supports 8 levels of software-controlled brightness. 🔅
• Minimal Pins: Unlike raw 7-segment displays that require 12+ pins, this module only needs 2 digital pins from your MCU. 🤏
• Clear Visibility: High-contrast LEDs that are easy to read from a distance. 👀

🚀 Example Library

For Arduino users, the most stable and widely used library is the Avishay Orpaz TM1637 Library. 📚

Note:

while the interface looks like I2C, it is actually a specific 2-wire protocol. you should use the dedicated TM1637 library rather than standard I2C scanners to detect it. 💡
