A 4x4 Rigid Matrix Keypad Module is a durable, tactile user-input panel designed for data entry, code entry, and system navigation in microcontroller projects. Unlike thin membrane keypads, this module features raised, hard plastic keys that provide distinct physical travel and crisp tactile feedback when pressed. Arranged in a 4-row by 4-column matrix, pressing any key bridges a specific row trace and column trace. The bottom edge features standard solder pad pads/pins for easy connection to microcontroller development boards.

This product is featured by Famephase Electronic Accessories as a robust, high-durability input solution for security lockboxes, access control panels, industrial interfaces, and custom keypads.
