Whadda WPM461 LED Display Module & Keypad with TM1638

The Whadda WPM461 LED Display Module & Keypad is a versatile and compact interface component for electronic projects, driven by the popular TM1638 controller. It integrates eight small seven-segment numeric displays, capable of showing both numbers and letters, alongside eight bright red status LEDs and eight responsive push buttons. This all-in-one module provides a complete user interface solution, allowing you to create interactive devices with visual feedback and user input in a single, easy-to-install package.

Connecting and programming the module is straightforward, thanks to its simple three-wire serial interface. This significantly reduces the wiring complexity compared to using individual displays, LEDs, and buttons, saving valuable time and I/O pins on your microcontroller. The module operates on a standard 5V DC supply, making it compatible with a wide range of development boards like Arduino, Raspberry Pi Pico, and other common microcontrollers.

Whether you're building a custom timer, a sensor readout display, a game controller, or a menu-driven control panel, this module offers a practical and professional-looking interface. The inclusion of decimal points on each display segment adds further functionality for showing precise numerical values. Its robust construction and clear labelling ensure reliable performance in prototyping, educational environments, and finished DIY electronics projects.
