Hw 130 Motor Control Shield For Arduino Datasheet Better -

The HW-130 uses the following :

void setup() pinMode(ENA, OUTPUT); pinMode(ENB, OUTPUT); pinMode(IN1, OUTPUT); pinMode(IN2, OUTPUT); pinMode(IN3, OUTPUT); pinMode(IN4, OUTPUT);

This section answers your primary query for a "datasheet better" by providing the full technical breakdown of the HW-130. Below is a complete specification sheet derived from the L293D chip's official data and the shield's common implementations. hw 130 motor control shield for arduino datasheet better

// HW-130 Motor Shield Test // Pins defined as per HW-130 mapping

The servo header shares the Arduino’s 5V regulator. A stalled servo (e.g., MG995) can draw 1A+ and instantly reset your Uno. Remove the +5V jumper and power servos from a separate 5V/3A UBEC. The HW-130 uses the following : void setup()

Proper powering is critical to avoid damaging your Arduino or the shield:

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 stalled servo (e

The shield has a terminal block (usually green screw terminals) labeled .

| Symptom | Likely Cause | Solution | |-----------------------------|----------------------------------|-------------------------------------------| | Motors not moving | No external battery | Connect VM to 6V–12V | | Motors move only one way | One H-bridge dead | Check pins IN1/IN2 or replace shield | | Servo twitches but no motion| Brownout from motor start | Separate 5V supply for servo | | Arduino resets when motors start | Battery voltage dips below 5V | Use higher voltage (9V) or bigger battery | | Shield gets very hot | Over current or stall | Reduce load, add heatsink fan | | PWM speed control has no effect | EN A/B jumpers missing? | No jumpers – these are direct pins. Check code pin numbers. |

The shield can also control a single bipolar or unipolar stepper motor using the AF_Stepper class.
