The TB6600 is a high-performance stepper motor driver designed to provide precise control of stepper motors. It is widely used in applications requiring accurate motion control, such as CNC machines, 3D printers, robotics, and automated machinery. The driver supports a wide range of input voltages (up to 42V) and can handle high current outputs (up to 4.5A), making it compatible with various stepper motor types. Its microstepping capability ensures smooth and precise motor operation, while its robust design ensures reliability in demanding environments.








The TB6600 driver is equipped with advanced features to meet the needs of precision motion control. Below are its key technical specifications:
The TB6600 driver has several input and output terminals for connecting to a microcontroller, power supply, and stepper motor. Below is the pin configuration:
| Pin Name | Description |
|---|---|
| PUL+ | Pulse signal input (positive terminal). Used to control motor steps. |
| PUL- | Pulse signal input (negative terminal). |
| DIR+ | Direction signal input (positive terminal). Determines motor rotation direction. |
| DIR- | Direction signal input (negative terminal). |
| ENA+ | Enable signal input (positive terminal). Activates or deactivates the driver. |
| ENA- | Enable signal input (negative terminal). |
| Pin Name | Description |
|---|---|
| A+ | Connects to the A+ coil of the stepper motor. |
| A- | Connects to the A- coil of the stepper motor. |
| B+ | Connects to the B+ coil of the stepper motor. |
| B- | Connects to the B- coil of the stepper motor. |
| Pin Name | Description |
|---|---|
| VCC | Connects to the positive terminal of the DC power supply (9V to 42V). |
| GND | Connects to the ground terminal of the DC power supply. |
Below is an example of how to control a stepper motor using the TB6600 driver and an Arduino UNO:
// Define control pins for the TB6600 driver
#define PUL_PIN 2 // Pulse signal pin
#define DIR_PIN 3 // Direction signal pin
#define ENA_PIN 4 // Enable signal pin
void setup() {
// Set control pins as outputs
pinMode(PUL_PIN, OUTPUT);
pinMode(DIR_PIN, OUTPUT);
pinMode(ENA_PIN, OUTPUT);
// Enable the driver
digitalWrite(ENA_PIN, LOW); // LOW enables the driver
}
void loop() {
// Set motor direction
digitalWrite(DIR_PIN, HIGH); // HIGH for one direction, LOW for the other
// Generate pulses to move the motor
for (int i = 0; i < 200; i++) { // 200 steps for one revolution (example)
digitalWrite(PUL_PIN, HIGH); // Pulse HIGH
delayMicroseconds(500); // Adjust delay for speed control
digitalWrite(PUL_PIN, LOW); // Pulse LOW
delayMicroseconds(500); // Adjust delay for speed control
}
delay(1000); // Wait 1 second before reversing direction
// Reverse motor direction
digitalWrite(DIR_PIN, LOW);
for (int i = 0; i < 200; i++) {
digitalWrite(PUL_PIN, HIGH);
delayMicroseconds(500);
digitalWrite(PUL_PIN, LOW);
delayMicroseconds(500);
}
delay(1000); // Wait 1 second before repeating
}
