產品概述

This is an electronic cigarette circuit board triggered by an airflow sensor for smoking and with adjustable power. It has dual outputs and is mainly composed of the following circuit modules: MCU控制模塊, dual power output module, OLED display screen, colorful light module, 充電管理模塊, 和鋰電池控制模塊. It can detect smoking actions and control the output through MCU, and display the output wattage and output status through a digital tube.

功能亮點

MEMS airflow sensor: The microphone airflow sensor detects changes in air pressure and identifies user smoking behavior.
信號處理: The airflow changes captured by the sensor will be converted into capacitance change signals, which will be processed by the ASIC chip and transmitted to the MCU control module for output control.
保護功能: 該PCBA解決方案板具有多個保護功能，以確保使用過程中的用戶安全, including lithium battery protection, 吸煙超時保護, 過度保護, 短路保護, 和低電池保護
模塊形式: SMT包裝用於形成模塊表單, 這使其可以直接焊接到電路上, 使其非常適合PCBA集成, 從而降低組裝成本並提高生產效率.
