Product introduction:
The module is a capacitive touch-type touch switch module based on a touch detection IC (TTP223B). Normally, the module outputs a low level, and the mode is a low power mode; when the corresponding position is touched with a finger, the module outputs a high level, and the mode switches to a fast mode; when there is no touch for 12 seconds, the mode is switched to a low mode.
