3 Wire 8 Bits Seven Segment LED with 16 way Keyboard Module TM1638

The 3-Wire 8-Bits Seven Segment LED with 16-Way Keyboard Module TM1638 is a versatile and efficient module commonly used in electronics projects, particularly for creating user-friendly displays and interfaces. This module combines an 8-digit seven-segment LED display with a 16-button tactile keypad, making it perfect for projects requiring numerical or alphanumeric output as well as user input. The TM1638 chip controls the LEDs, offering easy control through only three wires, significantly reducing the number of required connections.

The seven-segment display allows clear and bright visualization of numbers or characters, which can be controlled and updated through a microcontroller. The 16-way keypad provides tactile feedback and is ideal for applications like password input, controlling devices, or selecting options in user interfaces. The module is typically powered by 5V and is compatible with popular microcontrollers like Arduino, offering simple integration with pre-built libraries. This makes it an excellent choice for beginners and professionals alike who are working on projects such as digital clocks, counters, or interactive systems.
