Il. Product Features 

1. No Mechanical Wear: No mechanical components, eliminating wear and tear issues. It has an almost unlimited service life, which helps reduce later-stage maintenance costs. 

2. Flexible Environmental Adaptation: The sensing part can be installed behind any insulating layer (usually glass or plastic). This makes it easy to create a keyboard that is tightly sealed with the surrounding environment, achieving moisture-proof and waterproof effects. 

3. Highly Customizable Appearance: The panel pattern, as well as the size and shape of the keys, can be freely designed. Elements such as characters, trademarks, and perspective windows can be flexibly matched, enhancing the overall aesthetics and integrity of the product. 

4. Strong Durability: Compared with traditional physical keys, it is less prone to damage, ensuring stable performance in long-term use. 

5. Adjustable Signal Output: By modifying the resistor on the back of the module, the signal output can be adjusted to either latch output or level-holding output (see section 3.3.2 for detailed operation). 

6. Wide Voltage Support & Direct Driving: Supports an input voltage range of +2.7V ~ +6V and provides a +3.3V signal output. It can directly drive devices such as relays, optocouplers, and LED lights without additional drive circuits. 

7. Wide Temperature Adaptation: Operates normally within a temperature range of -30~+70℃, adapting to most indoor and outdoor application environments. 

8. Good Response Performance: Sensitive to touch operations, with no lag, delay, flickering, or other issues, ensuring a smooth user experience. 

9. Strong Anti-Interference Ability: Built-in anti-interference algorithms, which can effectively resist external electromagnetic interference and ensure stable signal transmission.
