Hw 130 Motor Control Shield For Arduino Datasheet !free! Direct

Up to (connected to Arduino’s dedicated timers).

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.

Ensure the external battery ground is connected to the GND pin on the terminal block, and that the external battery ground is also connected to the Arduino GND. 6. Software: Using the AFMotor Library

Summary

0.6A per bridge (1.2A peak) with thermal protection. Voltage: Wide range from 4.5V to 25V DC.

This shield utilizes specific Arduino pins to control the motors. If you attach the shield, these pins on the Arduino are occupied.

The shield uses two independent L293D motor driver chips paired with a 74HC595 shift register to optimize the Arduino's limited input/output (I/O) pins.

These connect to your DC motors or stepper motors. M1 and M2 form one block; M3 and M4 form the second block.

The HW-130 is a clone of the (similar to the Adafruit design). It allows independent control of up to 4 DC motors or 2 stepper motors + 2 servos. The datasheet is usually a 1–2 page PDF or a wiki-style schematic.

For advanced users, the 74HC595 shift register allows the L293D’s enable and direction pins to be controlled with only three GPIOs (data, clock, latch). This is why the shield leaves most Arduino pins free for other uses.

Here is a simple sketch to test the shield with two DC motors. This code does not require an external library, though using the standard AFMotor library is common if the shield is compatible (sometimes HW-130 requires custom code as below).

A single chip that converts serial data from the Arduino into parallel data to control the L293D pins. This saves Arduino pins. Ensure the external battery ground is connected to
