The main features and advantages of the audio capacitive touch Booster Pack are:
Get complete OLED user interface and MP3 recording/playback software library support, which can simplify development work.
In the mid-range smartphone industry, improving the user interface is key to the success of new models.
Typical relaxation oscillator topology structure. Capacitive sensors are composed of two adjacent copper pads or copper wires with a certain distance on a regular electronic circuit printed circuit board (PCB).
The circuit and waveform for frequency measurement. Frequency measurement refers to using a gate controlled timer to measure the frequency of a relaxation oscillator over a fixed period of time (Figure 2).
Advanced high cell density trench technology with ultra-low gate charge and excellent CdV/dt effect reduction
