2. Key Advantages & Features

• Dual Speed Regulation Modes: Seamlessly adjust motor speed using either 0.1V - 5V Analog Voltage or 1kHz - 20kHz PWM duty cycle (0-100%) inputs. Fully compatible with Arduino, STM32, or PLC controllers.

• Built-in Speed Signal Output: Features a dedicated "Signal" pin that outputs a real-time 5V speed pulse (push-pull output) for closed-loop monitoring.

• Industrial-Grade Protection: Built-in Overvoltage (O.V) and Undervoltage (L.V) safeguards to ensure long-term reliability in demanding environments.

• Ultra-Compact & Flexible: Measuring just 63mm x 42.5mm, it fits easily into tight enclosures or customized product assemblies.

• Dual Speed Regulation Modes: Seamlessly adjust speeds using standard 0-5V Analog signals or 1-20kHz PWM duty cycles, allowing easy integration with Arduino, STM32, or PLCs.
• Industrial Grade Protection: Integrated Overvoltage (O.V) and Undervoltage (L.V) safeguards prevent electrical damage during voltage spikes or sags.
• Real-time Speed Feedback: Built-in "Signal" pin outputs a precise 5V speed pulse (push-pull) for closed-loop speed tracking.
• Ultra-Compact Footprint: Measuring just 63mm x 42.5mm, it fits easily into tight enclosures or customized product assemblies.

• Thermal Management: If your brushless motor's rated power is below 60W, standard ventilation is sufficient. If the continuous motor power exceeds 100W, a suitable heatsink (aluminum or copper) must be securely mounted onto the driver MOSFETs. Ensure adequate electrical insulation between the MOSFET thermal pad and the heatsink.
• External Output Restriction: The 5V output port is reserved strictly for local speed potentiometers and direction switches. Connecting high-load external devices to this pin will burn out the internal LDO.
• Sensorless Compatibility Tuning: While designed as a universal 3 phase bldc motor controller, some sensorless motors may experience startup jitter or large no-load currents depending on their inductance/resistance profiles. In such cases, tuning the peripheral resistor/capacitor values on the board can solve start-up failures under load.
• Wiring Distance: If the distance between the driver board and the motor exceeds 50 cm, shielded cables must be used to mitigate high-frequency EMF interference.
