Complete Guide and Datasheet for the HW-130 Motor Control Shield for Arduino
For any serious project with motors exceeding 700 mA, consider upgrading to a MOSFET-based shield, but for light robotics and classroom work, the HW-130 remains a reliable workhorse.
When stacked onto an Arduino Uno, the HW 130 automatically connects to the following digital pins: hw 130 motor control shield for arduino datasheet
8-bit serial-to-parallel shift register used to expand Arduino pins. Voltage Range: Supports motor voltages from 4.5V to 24V (though often recommended up to 12V for generic versions). Output Current: continuous current per channel ( ) with thermal shutdown protection. 5.imimg.com Driving Capabilities
The shield is designed to plug directly into an Arduino Uno or Mega, utilizing specific pins while leaving others free for sensors. L293D Based Arduino Motor Shield
Detect stalls, measure load, or implement torque limiting. Up to 2 stepper motors (unipolar or bipolar,
