Product overview

This is an electronic cigarette circuit board that uses button knobs to adjust the output voltage and has LED light display and voice broadcast. It mainly consists of the following circuit modules: MCU control module, power output module, digital tube display and LED light display, charging management module, and lithium battery control module. The button adjustment module can recognize the user's button operation to smoke through LED and voice broadcast, 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.

LED/Display Status	working condition	Voice+LED display
	Post	The LED light strip lights up in the order of red, green, and blue
	Pre-heating	Start up and enter preheating mode. Preheat according to the gear temperature for 5 Minuten. During the preheating period, the LED strip indicator lights up at a rate of 7 scrolling lights per minute, and all lights up. The preheating end will be announced with a voice prompt. During the preheating process, the temperature can be adjusted at any time. After the preheating is completed, the light strip should follow a breathing cycle of 5.5 Sekunden.
	Turn on/off	1. Power on: Press and hold the knob for 2 seconds to turn on the device, and the startup voice will be broadcasted. The indicator light on the strip will light up one by one from low to the current battery level.
	Gear temperature control function	2. Shutdown: Turn off the Changan knob for 2 Sekunden, and the indicator light on the LED strip will turn off the battery's current level position one by one, and the shutdown voice will be broadcasted. "
	Standby function	1. Use the knob to adjust the temperature range between 180-330 ℃.
	Overcurrent or short circuit protection	2. Rotate clockwise to increase temperature. The light strip lights up from both sides towards the middle to the set gear, and the color of the light strip is yellow.
	Battery undervoltage before smoking	3. Rotate counterclockwise to reduce temperature. The light strip turns off from the middle to both sides at the set gear, and the color of the light strip is yellow. "
	Battery undervoltage after cigarette lighting	When not in use, the temperature drops by 5 degrees Celsius every 5 Sekunden, with a maximum decrease of 20% of the set temperature and maintained.
	Normal charging	Re suction the temperature and increase the full power to the set temperature. "
