Where to Find the "HW 130 Motor Control Shield for Arduino Datasheet Free" – Final Verdict

To summarize your search:

  • No single PDF exists called "HW130.pdf" from an official source.
  • The definitive free datasheet = TI L293D datasheet + this article's pinout/power tables.
  • Best community resource: Arduino Forum thread "HW-130 motor shield – known issues".

Pro tip: Bookmark this page. Print the pinout section. Tape it to your toolbox. The HW 130 is a capable shield if you respect its 600mA limit. Use external power for anything above two small DC motors.

HW-130 Motor Control Shield (also widely known as the L293D Motor Driver Shield

) is a classic entry-point for makers building robots with an Arduino Uno The HW-130 Motor Control Shield (also known as

. Here is a story of a typical project development using this hardware. The Spark: A DIY Robot Car

A student decides to build their first 4-wheel robotic car. They choose the HW-130 shield because it "shields" the

from the high power demands of motors that would otherwise "brown out" the microcontroller. The Setup: Mapping the Hardware The student consults the L293D Shield Datasheet to understand the pinout and power requirements: Motor Capacity : It can handle up to 4 DC motors 2 stepper motors : Two L293D dual H-bridge chips provide per channel ( peak) and handle voltages from : It uses a 74HC595 shift register

to expand just a few Arduino pins into eight motor control lines. The Build: Wiring and Power : The shield is pressed directly onto the Arduino Uno External Power : To avoid damaging the Arduino, the student removes the power jumper and connects a separate battery to the shield's terminals. : Four DC motors are screwed into the terminals labeled M1, M2, M3, and M4 The Code: Bringing it to Life The student installs the AFMotor Library . They write a simple loop: Connect boards, shields, and carriers - Arduino Help Center No single PDF exists called "HW130

Here’s a concise, interesting “datasheet-style” summary for the HW-130 Motor Control Shield (often sold as a clone of the L298N-based Arduino shield). This is formatted for easy reading and homework submission.

6. Limitations & Warnings (from practical use)

  1. No built-in flyback diodes – The L9110S includes internal clamping diodes, but for inductive loads (motors), adding external Schottky diodes (1N5819) across motor terminals improves reliability.
  2. Current limit – Do not exceed 1.2A peak. Motors drawing >800mA continuously may cause thermal shutdown.
  3. Heat dissipation – The IC is in SOP-8 package with no heatsink. Prolonged stall current will destroy the chip.
  4. Shield stacking – This shield does not pass through all Arduino pins (e.g., A0-A5 are usually unbroken). Check compatibility if stacking other shields.

4. Hardware Setup

  1. Stacking: Stack the shield onto the Arduino headers firmly.
  2. Power:
    • USB Power: The Arduino can be powered via USB. The motors will draw power from the Arduino's Vin. This is suitable for small motors only.
    • External Power (Recommended): Connect a battery pack (6V–12V) to the screw terminal block on the shield (+ and -).
    • Jumper Settings: Ensure any power jumpers on the board are configured correctly. If using external power at the terminal block, usually, the jumper connecting Arduino Vin to Motor Power should be removed if the voltage exceeds 12V to protect the Arduino regulator.
  3. Motors: Connect your DC motors to the green screw terminals (M1 and M2).
