74HC595 (Used to expand pins for motor control) Input Voltage (Motor Power): 4.5V to 25V DC
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 hw 130 motor control shield for arduino datasheet
This happens when motors draw too much current from the Arduino's 5V rail. Always use external power for the shield. 74HC595 (Used to expand pins for motor control)
The L293D chips can get hot. If you are drawing close to 600mA continuously, consider sticking a small aluminum heatsink onto the ICs. Conclusion Always use external power for the shield
These are the screw terminals for DC motors. Stepper 1: Uses M1 and M2. Stepper 2: Uses M3 and M4.
The HW-130 is based on the , designed to provide bidirectional drive current for motors. Motor Driver IC: 2 x L293D
