Feature: 1. This is a mini sensorless three-phase brushless DC motor drive module, which uses high-quality chips and can operate at a wide voltage. 2. The power input has reverse polarity protection function and will not burn when reverse polarity is reversed. It is very suitable for DIY enthusiasts. 3. With LED indicator light to indicate working status, stable performance and long service life 4. Three-phase three-wire drive, three-phase four-wire small brushless motor, sinusoidal, bass, small size, multi-functional design, it is a compact brushless inverter 5. Shipped in independent electrostatic bag packaging, equipped with 5PIN cable Product specifications: Working voltage: DC5V-15V Working current: 1.5A continuously Peak: 2A Maximum control power: 15W Quiescent current: 0.005A (standby) PWM duty cycle: 1 percent -100 percent Precautions: 1. The power supply is DC, AC is not allowed. Please use the correct voltage and current according to the parameter range. There are many types of brushless motors, and we cannot guarantee that all brushless motors are suitable. Please ensure that the wiring is correct before powering on. 2. Please use a motor that matches the working voltage, current, and power. Otherwise, some adverse phenomena may occur that may burn out the main chip. Poor contact is strictly prohibited. 3. This driver cannot be used to drive brushed motors Due to different batches, the appearance, color, and printed words of the product may vary, which does not affect its use.
