The HW-130 Motor Control Shield boasts an impressive array of features that make it an attractive option for motor control applications. Some of its key features include:
Proper powering is critical to avoid damaging your Arduino or the shield: hw 130 motor control shield for arduino datasheet better
HW-130 Motor Control Shield (often referred to as the L293D V1 Motor Shield) is a versatile expansion board for the Arduino Uno and Mega. It acts as a bridge, allowing the low-power signals from your Arduino to control high-power motors without damaging the microcontroller. Technical Specifications The core of this shield consists of two L293D dual-channel H-bridge drivers 74HC595 shift register to manage I/O pins efficiently. Motor Capacity 4 DC motors with individual 8-bit speed selection. 2 stepper motors (unipolar or bipolar). 2 "hobby" servos (5V) connected to dedicated high-resolution timers. Power Ratings : Supports motors between 4.5V and 25V : Provides 600mA per channel (1.2A peak) with thermal shutdown protection. Safety Features The HW-130 Motor Control Shield boasts an impressive
Standard analogWrite() at 490Hz works fine, but the L298N hums. For silent operation, use Timer1 to set PWM to 15–20 kHz (inaudible). Technical Specifications The core of this shield consists
