Keypad 4x4 Matrix +4 Separate keyboard + 8 Separate LED Module

The 4×4 Matrix Keypad Module with 8 LEDs is a compact human-machine interface (HMI) module designed for Arduino, ESP32, STM32, Raspberry Pi, and other microcontroller platforms. It combines a 16-key matrix keypad, four independent push buttons, and eight user-programmable LED indicators on a single PCB, making it ideal for embedded systems, control panels, access control, and user input applications. The module operates from a 3.2V to 5V power supply and features standard GPIO interfaces for easy integration with development boards. Mounting holes and included standoffs allow secure installation inside enclosures or prototype systems. The matrix keypad minimizes GPIO usage, while the additional buttons and LEDs provide expanded functionality for custom user interfaces.
