4X4 微動開關 矩陣鍵盤模組 16 外擴鍵盤模組

16鍵觸覺鍵盤矩陣，這是一個4×4矩陣的觸覺按鈕，牢固地安裝在PCB上，帶有一個8針單排0.1英寸間距接頭。開關清晰編號，帶有白色絲網印刷。每個開關在按下時都能提供令人滿意的觸覺反饋。0.1“單排公頭是麵包板友好的.PCB的整體尺寸為39mm x 43mm。這是在Arduino上試驗矩陣解碼的好方法！

16-Button Tactile Keypad Matrix

This is a 4×4 matrix of tactile buttons solidly mounted on to a PCB with an 8-pin single-row 0.1″ pitch header. The switches are clearly numbered with white silkscreen printing. Each switch gives satisfying tactile feedback when pressed.

The 0.1″ single row male header is breadboard friendly. The overall dimensions of the PCB are 39mm x 43mm.
This is a great way to experiment with matrix decoding on the Arduino!
