3x4 Phone-style Matrix Keypad Category_Display & LED/LED Strips there is room to plugHey, Jenny, I've got your number! And I'm going to dial 867 5309 into this very nice phone style matrix keypad. This keypad has 12 buttons, arranged in a telephone line 3x4 grid. It's made of plastic with sturdy plastic buttons. The keys are connected to a matrix so you only need 7 microcontroller pins (3 columns and 4 rows) to scan through the pad. It's basically a sturdier version of our Membrane 3x4 Matrix Keypad and comes with 7 or 8 header pins
