Brushless Motor PWM Speed Control Board
This DC brushless motor speed controller supports DC 8-24V input voltage. It outputs 5V PWM signal at about 18kHz frequency, with adjustable duty cycle ranging from 0% to 100%.
The board is equipped with a speed control potentiometer, start/stop switch and forward/reverse rotation switch. The forward and reverse function is only available when the matched brushless motor itself supports positive and reverse rotation.
⚠️ Important Note: This control board is only suitable for brushless motors with built-in driver and independent PWM signal terminal. It cannot directly drive brushless motors without an onboard driver.
