TM1637 4-Bit Digital Tube LED Display Module (Red)

The TM1637 4-Bit Digital Tube LED Display Module is a compact, energy-efficient, and easy-to-use display solution designed for Arduino, microcontrollers, and embedded systems. Featuring a high-quality 7-segment LED display, this module is ideal for digital readouts, counters, clocks, and timer-based applications.

At the heart of this module is the TM1637 driver chip, which simplifies control and reduces the number of required connections. Unlike standard 7-segment displays that demand multiple I/O pins, the TM1637 module uses only two pins (DIO & CLK) for communication, making it an excellent choice for projects where GPIO pin conservation is essential.

The bright red LED digits ensure excellent visibility in various lighting conditions, while the module’s I2C-compatible communication allows for seamless integration with microcontrollers like Arduino, Raspberry Pi, and ESP8266/ESP32. Additionally, its compact design and M2 screw positioning holes make it easy to mount onto circuit boards, enclosures, or DIY setups.

Key Features:

• TM1637 driver chip enables simple and efficient control.
• 4-digit, 7-segment LED display for crisp and clear numeric output.
