The HW-130 features a dedicated terminal for external power. Because Arduino pins cannot provide enough current for motors, you should connect an external battery pack (typically 6V–12V) to the terminals.
Remove the if using a separate power supply for the motors. Basic Code Example:
This datasheet and guide will cover the specifications, pinouts, and practical usage of the HW-130. 1. Technical Specifications hw 130 motor control shield for arduino datasheet
600mA per channel (1.2A peak non-repetitive) Output Channels: 4 Bi-directional DC motors with 8-bit speed selection. 2 Stepper motors (unipolar or bipolar). 2 Servo motors (5V high-resolution timers). Protection: Thermal shutdown and internal ESD protection. Dimensions: 69mm x 53mm x 14mm. 2. Key Hardware Features Power Terminal Blocks
The HW-130 Motor Control Shield is an essential "bridge" for robotics. While it uses an older L293D architecture, its ease of use and compatibility with the Adafruit library make it the go-to choice for students and hobbyists building their first motorized creations. The HW-130 features a dedicated terminal for external power
These are the screw terminals for DC motors. Stepper 1: Uses M1 and M2. Stepper 2: Uses M3 and M4.
Standard 3-pin headers connected to Arduino’s digital pins 9 and 10. 3. Pin Mapping and Conflicts Basic Code Example: This datasheet and guide will
74HC595 (Used to expand pins for motor control) Input Voltage (Motor Power): 4.5V to 25V DC
To simplify coding, it is standard practice to use the . Wiring Steps: Plug the HW-130 shield directly onto your Arduino Uno. Connect your DC motor wires to the M1 terminal.
