- Product overview
Smart Control Circuit Board for E-Cigarettes
This CBD e-cigarette circuit board adjusts output voltage via buttons and shows data on a digital display. It includes an MCU control module, power output module, digital and LED display, charging management, and lithium battery control. The button module detects each press to simulate smoking activity. It then displays the real-time status on the screen, helping users monitor usage.
Functional Highlights
- Signal Processing Function: The system detects button signals to identify user smoking behavior. The MCU receives the signal and activates the output module for heating.
- User Operation Detection: The system detects key signals to identify smoking actions. The MCU receives the signals and activates the output module for heating.
- Comprehensive Protection Features for Safe Vaping: This CBD e-cigarette circuit board includes multiple safety features to protect users during use. It provides lithium battery protection to prevent overcharging or damage. Smoking timeout protection limits continuous usage for added safety. Over-temperature protection prevents overheating during extended sessions. Short circuit protection ensures stable performance under abnormal conditions. Low battery protection alerts users before power runs out.
- Module Form with SMT Packaging: We use SMT packaging to form the module structure. This allows direct soldering onto the main circuit board. It integrates easily into PCBA systems with minimal effort. As a result, it reduces assembly costs and boosts production efficiency.
