4 bi-directional DC motors with 8-bit speed selection (~0.5% resolution).
The HW-130 shield requires the legacy library to work seamlessly. You can install this via the Arduino IDE Library Manager (search for "Adafruit Motor Shield V1 library").
Proper power management is critical when using the HW-130 to prevent resetting or damaging your Arduino. Option A: Shared Power Supply (Short-Term/Low Load Only) Leave the PWR Jumper on the board connected. hw 130 motor control shield for arduino datasheet free

The Arduino and the motor shield share the same power source. Power supplied to the Arduino DC jack will also power the motors (Only recommended for low-power, 5V-9V motors).
In this article, we provide a complete, free breakdown of the HW 130 datasheet. By the end, you will understand every technical detail required to get this shield moving. Proper power management is critical when using the
The shield uses a shift register to save Arduino pins, requiring only a few digital pins to control all 8 H-bridge directions. Arduino Pins Used Digital Pin 9 Digital Pin 10 DC Motors / Steppers Digital Pins 4, 7, 8, and 12 (via 74HC595) PWM (Speed Control) Pins 11 (M1), 3 (M2), 5 (M3), 6 (M4) Unused/Free Pins Digital Pin 2, Pin 13, and Analog Pins A0–A5 Power Management The HW-130 features a power jumper
The shield simplifies wiring by bringing out most Arduino pins to terminal blocks and headers. L293D Based Arduino Motor Shield
(often based on the L293D or L298P chipset) is a popular, modular solution designed specifically to plug directly into an Arduino R3 pinout, making motor control accessible and straightforward .
The official Arduino forum and many regional forums contain threads about the HW‑130. These threads often include troubleshooting guides, alternative wiring diagrams, and user‑shared code that can serve as a practical datasheet. Notable examples include:
