Up to (unipolar or bipolar) with single, double, interleaved, or micro-stepping.
Below is a simple test script to run a DC motor on port M1 forward and backward.
Practical tips
. It is designed to simplify the complex task of driving high-current inductive loads, such as DC motors, steppers, and servos, which the Arduino’s standard I/O pins cannot handle directly. Core Technical Specifications hw 130 motor control shield for arduino datasheet free
: Two L293D dual H-bridge motor drivers and one 74HC595 shift register. Output Channels 4 bi-directional DC motors with individual 8-bit speed selection. 2 stepper motors (unipolar or bipolar). 2 dedicated headers
The shield integrates two L293D chips and one 74HC595 shift register to minimize the number of Arduino pins used.
This section provides a simple walkthrough for setting up the Go to product viewer dialog for this item. to control two DC motors. Required Components Arduino UNO R3 or equivalent. HW-130 Motor Control Shield. DC Motors. External Power Supply ( 7.4V7.4 cap V Battery Pack). Step-by-Step Setup Up to (unipolar or bipolar) with single, double,
Press the HW-130 pins firmly into the headers of your Arduino board [1].
Using the HW-130 Motor Control Shield is relatively straightforward. Here's a step-by-step guide:
Some HW-130 variants use pins D3, D4 (Motor A) and D5, D6 (Motor B) . Always verify with a multimeter or test sketch. It is designed to simplify the complex task
Advantages and limitations
The L293D chips can get hot when drawing close to 600mA continuous current [1]. Consider sticking mini aluminum heatsinks onto the chip surfaces if you run heavy loads.
for 5V "hobby" servos connected to the Arduino's high-resolution timers. Power Ratings :
Wire an external battery pack or power supply (e.g., a 2S LiPo or 4 x AA battery holder) to the EXT_PWR terminals [1]. Ensure correct polarity (+ to +, - to -).
