HI, Button matrices can quickly become unreliable if the PCB routing, scanning logic, and anti-ghosting design aren’t handled correctly. I can design a clean button-matrix PCB with proper row/column routing, diode protection, and microcontroller interface so the keypad works reliably and is easy to integrate into your embedded system. 1️⃣ How many buttons and matrix size are required (e.g., 3×4, 4×4, larger)? 2️⃣ Which microcontroller or embedded platform will interface with the PCB? 3️⃣ Do you need schematic + PCB layout + manufacturing files (Gerber/BOM)? Warm regards, The Blend Nation.
