74HC595 (Used to expand pins for motor control) Input Voltage (Motor Power): 4.5V to 25V DC
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 hw 130 motor control shield for arduino datasheet
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 74HC595 (Used to expand pins for motor control)
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. 2 Servo motors (5V high-resolution timers)
If the jumper is shorted, the Arduino and the motors share the same power source. It is highly recommended to remove the jumper and use separate power supplies to avoid resetting the Arduino due to voltage spikes. Motor Connections
Pins 2 and 13 are usually free, along with the Analog pins (A0–A5), which can also be used as digital I/O for sensors. 4. How to Use the HW-130 with Arduino
