Driving PWM Speed Control Board Brushless Speed Controller

Product Overview

This Brushless Motor Speed Controller Board provides precise speed modulation and directional control for BLDC motors. Equipped with an onboard potentiometer, dual tactile switches, and multiple signal outputs, it acts as an efficient PWM signal generator. It is ideal for driving brushless fans, pumps, and motors that require external control inputs.

Key Features & Functions

·        Multi-Function Terminal Block: Features a 6-pin terminal interface for versatile integration:

   CW/CCW: Controls the direction of motor rotation (Clockwise / Counter-Clockwise).

o      BRK: Brake control input/output to quickly stop the motor.

o       PWM: Outputs the Pulse Width Modulation signal to control motor speed.

o      +5V: Auxiliary 5V power output to power external sensors or low-power logic components.

o      GND: Common Ground reference.

o       VCC: Main power supply input (complemented by an onboard 78M05 voltage regulator for stable internal logic power).

·        Dual Power Input Options: Includes both the main 6-pin terminal array and a dedicated 2-pin blue terminal block for easy power supply connection.

·        Onboard Potentiometer: Features a rugged, side-mounted dial potentiometer for smooth, real-time manual adjustment of the PWM duty cycle (speed control).

·        Dual Tactile Control Switches: Two onboard micro-switches (labeled K1 and K2) allow for quick toggling of modes, direction, or start/stop functions directly on the board.

·        Robust Signal Conditioning: Built with an integrated circuit (IC) central driver, high-quality SMD resistors, ceramic capacitors, and a heavy-duty electrolytic filter capacitor to ensure low-noise signal generation and voltage stability.
