Hw 130 — Motor Control Shield For Arduino Datasheet Better Fix

Arduino powered via USB – the shield’s green LED (near VM) should light. If not, remove battery and check polarity.

The shield is a clone of the now-discontinued Adafruit Motor Shield V1. The core of the HW-130 is the integrated circuit, a quadruple high-current half-H driver chip. The L293D is a classic choice for hobbyist motor control because of its simplicity and robustness.

with individual 8-bit speed selection (connected to terminals M1, M2, M3, M4). Up to 2 stepper motors (unipolar or bipolar). hw 130 motor control shield for arduino datasheet better

These three-pin headers provide a convenient way to connect up to two standard 5V servos. They are usually connected to digital pins 9 and 10.

A standard motor driver needs two Arduino pins per motor. This shield uses the shift register to control the L293D chips using only 3 pins (Data, Latch, Clock) from the Arduino, freeing up the rest of your pins for sensors. Arduino powered via USB – the shield’s green

Designed for Arduino Uno, Mega, and Duemilanove. Capacity & Connections The shield can simultaneously control:

The is a popular L293D-based expansion board designed for the Arduino Uno and Mega. It is functionally identical to the original Adafruit Motor Shield (v1) and is often referred to as a "clone". Core Specifications The core of the HW-130 is the integrated
