Matrix Membrane Keypad 12 or 16 Keys for Arduino

✅ Choose the key count. A 12-key or 16-key version lets you match the panel to the input your project needs.

✅ Enter values by hand. Physical buttons give the build a dedicated surface for menu and value entry.

✅ Keep controls together. A grouped membrane panel replaces a separate switch for every button.

✅ Wire the matrix. The matrix layout connects to compatible Arduino, ESP32 and DIY control projects.
