Separate power input for motors to protect the Arduino. 2. Technical Specifications & Datasheet Data Driver IC: 2 × L293D (Quadruple Half-H Drivers). | Parameter | Rating | Notes | |

| Parameter | Rating | Notes | | :--- | :--- | :--- | | | L293D | Provides bi-directional control. | | Operating Voltage | 4.5V – 25V | Supplied via the External Power Terminal block. | | Logic Voltage | 5V | Supplied by the Arduino via the USB or Vin. | | Output Current (Per Channel) | 0.6A (Continuous) | Max peak current is 1.2A per channel. | | Total Max Current | ~1.2A – 1.5A | The L293D gets hot quickly above 0.5A. | | Number of Motors | 4 DC Motors OR 2 Stepper Motors | Cannot run 4 steppers, only 2. | | Servo Ports | 2 | Connected directly to Arduino Pins 9 and 10. | | Thermal Protection | Yes | Built into the L293D, but use a heatsink for high loads. | | | Output Current (Per Channel) | 0

| Problem | Likely Cause | Solution | | :--- | :--- | :--- | | | No power to shield, incorrect wiring, or missing library | Check EXT_PWR connection, ensure motor is in M1/M2, and verify AFMotor library is installed | | Motors spin but Arduino doesn't boot/resets | Motor power brown-out | Remove PWR jumper, ensure external power can supply enough current, separate motor and logic supplies | | Weird/unexpected motor behavior | Shift register not powered or damaged | Ensure shield is seated properly, check if 74HC595 chip is getting 5V, try a different Arduino pin | | Bluetooth module not pairing | Wrong baud rate, power issues | Check baud rate (usually 9600 or 38400), ensure BT module is getting enough current (use external 5V regulator if needed) | | Servo jitters randomly | Servo power drawn from Arduino 5V rail | Power servos from a separate 5V regulator connected directly to battery pack |

Here are several things to avoid when working with your HW-130 shield:
