ACEBOTT Large Capacitive Touch 4*4 Matrix Keypad Module Easy-Plug Compatible with ESP32/Arduino

The ACEBOTT Large Capacitive Touch 4*4 Matrix Keypad Module is an input device used to input data into a computer or other electronic device. Each key of this Matrix Keypad Module is a capacitive touch design, with a layout of four rows and four columns, and each key represents a specific character. When a finger touches a key, it causes a corresponding change in the capacitance of the touch key. Once the detection circuit connected to the key detects this capacitance change, it outputs information that the corresponding key has been pressed.

Application reference: password doors, calculators, ATM machines, mobile phones, etc.
