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 (often referred to interchangeably with the L293D Motor Drive Shield) is one of the most versatile and affordable tools for hobbyists looking to add motion to their Arduino projects. Whether you are building a four-wheel-drive robot, a pan-tilt camera system, or a basic CNC machine, this shield provides the necessary power handling to bridge the gap between delicate microcontrollers and power-hungry motors.

This datasheet and guide will cover the specifications, pinouts, and practical usage of the HW-130. 1. Technical Specifications

This happens when motors draw too much current from the Arduino's 5V rail. Always use external power for the shield.

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.

Connect an external 9V battery or Li-ion pack to the block (observe polarity!).

Pins 2 and 13 are usually free, along with the Analog pins (A0–A5), which can also be used as digital I/O for sensors. 4. How to Use the HW-130 with Arduino

74HC595 (Used to expand pins for motor control) Input Voltage (Motor Power): 4.5V to 25V DC

Check the PWR jumper. If it's off and you haven't connected external power to the shield, the motors won't move even if the Arduino is on.

The L293D chips can get hot. If you are drawing close to 600mA continuously, consider sticking a small aluminum heatsink onto the ICs. Conclusion
