Hw 130 Motor Control Shield For Arduino Datasheet
The (often labeled as an L293D Motor Driver Shield) is a versatile, low-cost expansion board for the Arduino Uno and Mega. It is essentially a clone of the original Adafruit Motor Shield V1 , designed to drive inductive loads such as relays, solenoids, DC motors, and stepper motors. Key Technical Specifications
This happens when motors draw too much current from the Arduino's 5V rail. Always use external power for the shield.
Supports motor voltages from 4.5V to 12V (the L293D IC itself can handle up to 36V, but the shield components often limit it). hw 130 motor control shield for arduino datasheet

You need a plug-and-play solution to drive two small yellow DC motors (TT motors) or a small stepper motor for a CNC plotter, and you want to avoid messy wiring. The (often labeled as an L293D Motor Driver

user wants a long article for the keyword "hw 130 motor control shield for arduino datasheet". I need to provide comprehensive information about the HW-130 motor control shield, including a datasheet, specifications, features, pinout, usage, and applications. I should search for relevant information. search results show various sources. I need to open the most relevant ones to gather detailed information. I'll open result 0, result 2, result 3, result 4, result 5, result 6, result 7, and result 1 from the first search. search results provide various sources of information. I will also open result 5 from the second search, result 0 from the third search, and result 5 from the fifth search. search results for "HW-130" "datasheet" pdf and "HW-130" "L293D" shield pinout did not yield a specific datasheet, but they provide some relevant information. I will open result 0, result 1, result 2, result 3, result 4, and result 5 from the first search, result 0 from the second, result 0 from the third, result 5 from the fifth, result 0 from the second search, result 0 from the third search, result 5 from the fifth search, and result 0 from the second search. have gathered information from various sources. Now I need to write a comprehensive article. I'll structure it with an introduction, key features, specifications, pinout, programming, usage examples, troubleshooting, safety, and conclusion. I'll cite the sources. is a comprehensive guide to the HW-130 Motor Control Shield for Arduino, including a detailed breakdown of its features, specifications, pinout, and how to use it. Always use external power for the shield
| Arduino Pins | HW-130 Function | | :--- | :--- | | | Channel A Enable (L293D Enable 1,2) | | D5 | Channel A PWM / Speed Control (Logic High 1 & 2) | | D6 | Channel A Direction (Input 1) | | D7 | Channel A Direction (Input 2) | | D8 | Channel B Enable (L293D Enable 3,4) | | D9 | Servo 1 Control Signal | | D10 | Servo 2 Control Signal / Shift Register Latch | | D11 | Channel B PWM / Speed Control (Logic High 3 & 4) | | D12 | Channel B Direction (Input 3) | | D13 | Channel B Direction (Input 4) | | A0-A5 | Analog Inputs (Broken out for general use) | | 5V & GND | Logic Power |
To unlock the full potential of the HW 130, you must remove the ENA/ENB jumpers (JP2 and JP3). Without these jumpers, you manually control those pins via PWM.
