Hw 130 Motor Control Shield For Arduino Datasheet Link

The shield uses almost all digital pins on the Arduino Uno, which is a critical detail for planning your project. Arduino Pins Used Digital 9 and 10 DC/Stepper Motors Digital 3, 5, 6, 11 (PWM) Shift Register (74HC595) Digital 4, 7, 8, 12

600mA per channel (1.2A peak non-repetitive) Output Channels: 4 Bi-directional DC motors with 8-bit speed selection. 2 Stepper motors (unipolar or bipolar). 2 Servo motors (5V high-resolution timers). Protection: Thermal shutdown and internal ESD protection. Dimensions: 69mm x 53mm x 14mm. 2. Key Hardware Features Power Terminal Blocks hw 130 motor control shield for arduino datasheet

Check the PWR jumper. If it's off and you haven't connected external power to the shield, the motors won't move even if the Arduino is on. The shield uses almost all digital pins on

This happens when motors draw too much current from the Arduino's 5V rail. Always use external power for the shield. 2 Servo motors (5V high-resolution timers)
