Smart Pod System PCBA Board for Enhanced Vaping Control

This advanced pod system PCBA board powers modern e-cigarette devices. It features button-operated voltage adjustment and a clear digital display. The MCU control module ensures precise command execution. Its power output module delivers stable performance. Users can track device status instantly through digital and LED indicators. A reliable charging management module supports safe, fast recharging. The integrated lithium battery control enhances safety and efficiency. Every puff is detected via the button module and displayed in real time. Built for smooth function and intuitive use, this board upgrades the vaping experience with smart control and seamless performance.

Functional Highlights

Signal Processing: The MCU detects button signals to recognize smoking actions. Then, it instantly controls the output module for heating.
User Operation Detection: The MCU identifies smoking by analyzing key signals. After detection, it quickly triggers the heating process.
Safety Protection Functions: This pod system PCBA includes multiple safety protections. It offers a lithium battery, timeout, and over-temperature protection. It also prevents short circuits and protects during a low battery.
Module Structure: It uses SMT packaging for module formation. This allows direct circuit soldering without additional steps. As a result, it cuts assembly costs and boosts production efficiency.
