- 產品概述
This is an electronic cigarette circuit board that uses buttons to adjust the output voltage and has a digital display. It mainly consists of the following circuit modules: MCU control module, power output module, digital display and LED light display, charging management module, and lithium battery control module. The button module can recognize the user’s operation of smoking by pressing the button and display it through the digital display, so that the user can understand the device status when smoking.
Functional Highlights
- Signal processing: Identify user smoking by detecting button signals, and the MCU controls the output module to output heating after receiving the button signals.
- User operation judgment: Identify user smoking by detecting key signals, and the MCU controls the output module to output heating after receiving the key signals.
- Protection function: This PCBA solution board has multiple protection functions to ensure user safety during use, including lithium battery protection function, smoking timeout protection, over temperature protection, short circuit protection, and low battery protection.
- Module form: SMT packaging is used to form a module form, which allows it to be directly soldered onto the circuit, making it very suitable for PCBA integration, thereby reducing assembly costs and improving production efficiency.
