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
This happens when motors draw too much current from the Arduino's 5V rail. Always use external power for the shield.
The L293D chips can get hot. If you are drawing close to 600mA continuously, consider sticking a small aluminum heatsink onto the ICs. Conclusion hw 130 motor control shield for arduino datasheet
This datasheet and guide will cover the specifications, pinouts, and practical usage of the HW-130. 1. Technical Specifications
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. 600mA per channel (1
The HW-130 features a dedicated terminal for external power. Because Arduino pins cannot provide enough current for motors, you should connect an external battery pack (typically 6V–12V) to the terminals.
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 Protection: Thermal shutdown and internal ESD protection
The HW-130 is based on the , designed to provide bidirectional drive current for motors. Motor Driver IC: 2 x L293D
