Reliable Core for Smart Hookah Devices

Our hookah device PCBA module delivers powerful performance in a compact form. Designed for modern electronic hookah products, it integrates essential control, protection, and user interface functions in one board.

Precise MCU-Controlled System

The module features an advanced MCU that manages power output, airflow signals, and user interaction. It interprets button operations and airflow triggers, offering accurate control with real-time display feedback.

User-Friendly Digital Display

A built-in digital screen shows voltage levels and device status. Users can adjust the output with tactile buttons and monitor changes instantly during operation.

Robust Safety Protection Built-In

Safety is built into the core. The module includes:

Lithium battery protection
Overheat protection
Smoking timeout control
Short circuit prevention
Low battery alerts

These protections ensure a stable and secure vaping experience every time.

Efficient Signal Processing

Sensors detect airflow changes and convert them into capacitance signals. The ASIC chip processes these and relays them to the MCU for action. This ensures a fast and accurate response to every inhale.

Compact SMT Packaging for Easy Integration

The module uses SMT packaging, ideal for PCBA integration. Manufacturers can solder it directly onto their circuit boards, cutting down assembly time and cost.

Customizable and Scalable for OEM Projects

We support bulk orders and custom configurations. Whether you’re launching a new hookah device or upgrading existing systems, our PCBA module gives your product a high-tech edge.

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	First, power on to enter preheating mode. Then, preheat based on gear temperature for 5 minutes. During this time, adjust the temperature anytime. Meanwhile, the LED strip lights start scrolling. They display 7 scrolling lights per minute. At the same time, all indicator lights remain on. Next, a voice prompt announces preheating completion. Afterward, the light strip switches to breathing mode. Finally, it follows a 5.5-second breathing cycle.
	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 seconds, 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 of 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 seconds, with a maximum decrease of 20% of the set temperature and maintained.
	Normal charging	Re-set the temperature and increase the full power to the set temperature. “
