Keypad A Module provides versatile input functions. It can be directly controlled by Innovati's Basic Commander for various applications through simple connections. By setting different input modes, it can be configured rapidly to emulate various commonly used input interfaces, including the numeric input for the calculator, English character input for the mobile phone, the hexadecimal input for engineering, or even the user-defined returned value for each key. In addition to the input options, the debounce time can be set to avoid determining the mechanical bounce as key pressed. The automatic repeat (auto-repeat) input can be set for generating repeated input while press and hold the key.
