The BDTronics Bluetooth BLDC Fan Controller lets you control and monitor compatible brushless DC (BLDC) fans directly from an Android smartphone using Bluetooth Low Energy (BLE 5). Designed for convenient wireless operation, this smart fan controller allows users to switch the fan ON or OFF, adjust speed, change rotation direction between clockwise (CW) and counterclockwise (CCW), and monitor fan RPM through a dedicated Android application.

Developed by BDTronics for smart fan control applications, this compact controller operates from a 9V–30V DC input and features a 5-pin JST connector with 2.54 mm pin spacing. With a wireless control range of approximately 10 metres in open areas, it provides a convenient interface for compatible BLDC fan systems used in homes, workshops, electronics projects, and custom automation applications.

Features:

• Bluetooth BLE 5 Connectivity: Connects wirelessly to a compatible Android smartphone for fan control and monitoring.

• App Control: Operate compatible BLDC fans using the dedicated smart fan application.

• Fan ON/OFF Control: Switch the connected fan on or off from your smartphone.

• Adjustable Fan Speed: Change fan speed through the mobile application.

• CW/CCW Direction Control: Select clockwise or counterclockwise rotation when supported by the connected fan and motor driver.

• Real-Time RPM Display: View fan rotational speed in revolutions per minute (RPM), subject to the controller's supported feedback interface.

• Wireless Operation: Control the fan without a direct wired control connection to the smartphone.

• 10-Metre Control Range: Typical specified range of approximately 10 m in open areas; walls and electrical interference may reduce range.

• Wide DC Input: Supports a 9V–30V DC input supply.

• Compact Design: Measures 70 × 70 × 24 mm for convenient integration into compatible installations.

• 5-Pin JST Connector: Uses a 2.54 mm-pitch, 5-pin JST connection.

• Pre-Wired Connection: Includes a cable with an approximate length of 130 mm.

• Smart Fan Monitoring: Combines speed adjustment, rotation control, and RPM monitoring in one wireless control solution.

• BDTronics Smart Fan Solution: Designed for compatible BLDC fan control applications developed or integrated by BDTronics.

How to Use the Bluetooth BLDC Fan Controller

• Verify Compatibility: Confirm that your BLDC fan supports the controller's electrical interface and control functions. BLDC fans use different motor driver designs, so compatibility should be checked before connection.

• Prepare the Power Supply: Use a regulated DC power supply within the specified 9V–30V input range, following the controller's wiring requirements.

• Connect the Controller: Connect the 5-pin JST cable to the designated interface according to the correct pinout. Do not assume pin assignments without checking the product wiring documentation.

• Install the Android App: Install the compatible BDTronics Smart Fan application on an Android smartphone.

• Connect via Bluetooth: Power on the controller and use the application to discover and connect to the device.

• Turn the Fan ON or OFF: Use the app controls to switch the compatible fan on or off.

• Adjust Speed: Change the fan speed through the application's supported speed control interface.

• Change Rotation Direction: Select CW or CCW when the connected fan and driver support reversible operation.

• Monitor RPM: View the reported fan speed through the app when the RPM feedback signal is available and correctly connected.

Important Compatibility Notes

• This controller is intended for compatible BLDC fan systems; it should not be assumed to work with every BLDC motor or conventional AC fan.

• The 9V–30V specification refers to the controller's stated input supply range. Confirm the required fan supply voltage and power arrangement before installation.

• Reverse rotation requires support from the connected motor driver and fan. Not all BLDC fans support CW/CCW operation.

• RPM monitoring depends on the controller's supported speed feedback interface and compatible fan wiring.

• Bluetooth range depends on the installation environment, obstacles, antenna placement, and interference.

• Confirm the connector pinout before applying power to avoid damaging the controller or fan.
