Hw 130 Motor Control Shield For Arduino Datasheet Better -

L293D drivers have an internal voltage drop of roughly 1.5V-2V. A 9V input will only give about 7.5V at the motors.

The L298N’s thermal shutdown occurs at 70°C junction temp. On the HW-130, the heatsink is glued poorly, and airflow is blocked by the Arduino below. You will hit thermal rollback at 1.8A continuous in a 25°C room.

Supports external power for motors to prevent Arduino damage. hw 130 motor control shield for arduino datasheet better

The HW-130 has no official datasheet – it’s a clone of a clone. But now you know its soul: an L298N chip, a handful of diodes, screw terminals, and a heroic ability to get your robot moving. Treat it with respect for heat and power, and it will serve faithfully.

The is a low-cost, clone variant of the popular L293D-based motor shield (similar to the Adafruit or DFRobot designs). It is designed to drive: L293D drivers have an internal voltage drop of roughly 1

Here are the official and practical specifications for the HW-130 shield, as derived from its datasheet and community experience.
