Hw 130 Motor Control Shield For Arduino Datasheet Better ((exclusive)) Jun 2026

This comprehensive data sheet provides clear technical specifications, definitive pin allocations, and actionable implementation guidelines to help you optimize your hardware setups. Technical Specifications Matrix Specifications Notes / Constraints Dual L293D H-Bridge Quadruple high-current half-H drivers. Logic Shift Register 74HC595 8-bit Serial-In/Parallel-Out Saves physical Arduino digital I/O pins. Logic Voltage ( VSScap V sub cap S cap S end-sub ) 5V DC (Sourced from Arduino) Must maintain clean 5V to power the logic gates. Motor Supply Voltage ( VC1cap V sub cap C 1 end-sub / EXT_PWR) 4.5V to 25V DC (Safe Limit) Rated up to 36V on paper; 12V-15V practical limit. Continuous Current (Per Channel) 600 mA (0.6A) Adequate for standard yellow hobby gear motors. Peak Output Current 1.2 A (Non-repetitive pulse) Short bursts only; triggers thermal shutdown if held. Motor Capacities 4 DC Motors / 2 Steppers + 2 Servos Cannot run 4 DC motors and 2 steppers at the same time. Adafruit Motor Shield - L293D Lesson 01

void setup() stepper.setSpeed(60); // Set motor speed in RPM

: Pull-down resistors ensure motors stay disabled during Arduino power-up to prevent erratic movement. 5.imimg.com Pinout and Control Logic

: Used to expand control pins, meaning only a few Arduino pins are needed to control all four motor directions. hw 130 motor control shield for arduino datasheet better

This article fills those gaps.

Remove the 5V jumper and feed 5V from a reliable source (or Arduino’s 5V pin if current <200mA). This prevents back-EMF from resetting your Arduino.

for (int i = 255; i >= 0; i--) motor2.setSpeed(i); delay(10); Logic Voltage ( VSScap V sub cap S

void loop() Serial.println("Forward!"); motor1.run(FORWARD); // Run motor forward delay(2000); // for 2 seconds

There are two popular Adafruit motor libraries—V1 (for this shield) and V2 (for newer shields). Make sure you have installed the Adafruit Motor Shield V1 Library to match your HW-130 shield.

Here’s an example of a simple back-and-forth motion with an accelerating and decelerating speed ramp. This is a classic test for any motor control setup: Peak Output Current 1

speed = map(speed, 0, 255, 30, 255); analogWrite(ENB, constrain(speed, 0, 255));

void setup() BT.begin(9600); motor1.setSpeed(200); motor2.setSpeed(200);
