3x4 Phone-style Matrix Keypad Category_Display & LED/LED Strips Kendryte K210Hey, 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.
