Electric Shaver

Overview

Electric shaver offer a convenient and efficient alternative to traditional manual razors. They come in various models with different features, such as adjustable settings, battery-powered or rechargeable options, and additional attachments for trimming or shaping facial hair.

Feature Design

Firmware programming in electric shavers allows for customization of various features: The button can be programmed to turn the shaver on with one press, and off with another press. Alternatively, two adjustable settings can be considered, depending on factors such as the product's price range and target market. To provide users with visual feedback on battery life, a display screen can be incorporated. However, for those who prefer a minimalist design, the display screen can be omitted.

Microcontroller Selection

For the controller chip, it is recommended to use the YF co-packaged chip. This chip combines the charger, display, and the main control functions into a single unit, reducing the size of the printed circuit board (PCB). This not only cuts down on costs but also allows for a more compact electric shaver.
