The TB6600 is a stepper motor driver designed to provide precise control of stepper motors. It supports a wide range of input voltages (up to 40V) and can drive motors with high current ratings (up to 4.5A). This makes it an ideal choice for applications requiring accurate motor control, such as robotics, CNC machinery, 3D printers, and automated systems. The TB6600 is known for its reliability, ease of use, and compatibility with microcontrollers like Arduino and Raspberry Pi.

Write Control Code:
Below is an example Arduino sketch to control a stepper motor using the TB6600 driver:
// Define pin connections
const int stepPin = 3; // Connect to PUL+ on TB6600
const int dirPin = 4; // Connect to DIR+ on TB6600
const int enPin = 5; // Connect to ENA+ on TB6600
void setup() {
// Set pin modes
pinMode(stepPin, OUTPUT);
pinMode(dirPin, OUTPUT);
pinMode(enPin, OUTPUT);
// Enable the driver
digitalWrite(enPin, LOW); // LOW enables the driver, HIGH disables it
}
void loop() {
// Set motor direction
digitalWrite(dirPin, HIGH); // HIGH for one direction, LOW for the other
// Generate step pulses
for (int i = 0; i < 200; i++) { // 200 steps for one revolution (depends on motor)
digitalWrite(stepPin, HIGH); // Step pulse HIGH
delayMicroseconds(500); // Pulse duration (adjust for speed)
digitalWrite(stepPin, LOW); // Step pulse LOW
delayMicroseconds(500); // Delay between pulses
}
// Change direction
digitalWrite(dirPin, LOW);
delay(1000); // Wait 1 second before reversing direction
}
