Hw 130 Motor Control Shield For Arduino Datasheet Better __top__ Jun 2026

Because it uses a shift register, most motor control signals are handled internally. However, certain Arduino pins are "reserved" when the shield is plugged in. Arduino Pins Used Description 4, 7, 8, 12 Communicates with the 74HC595 latch. PWM Speed (DC) 3, 5, 6, 11 Controls motor speed via PWM. Servo 1 Digital Pin 9 Connects to the standard Servo 1 header. Servo 2 Digital Pin 10 Connects to the standard Servo 2 header. Analog Inputs Generally free for sensors or extra I/O. 3. Power Connection (Critical) L293D Based Arduino Motor Shield

If you use analogWrite() on pins 9, 10, 5, or 6, the PWM frequency is ~490Hz or ~980Hz depending on the board. The L298N works best below 25kHz, so this is fine—but the shield’s response becomes nonlinear below 30% duty cycle due to the H-bridge dead-time. A better datasheet would warn you. Because it uses a shift register, most motor

The is a popular, low-cost expansion board for the Arduino Uno and Mega, designed to drive a variety of motors simultaneously with minimal wiring. It is technically identical to the classic Adafruit Motor Shield v1 design and is powered by dual L293D dual-channel H-bridge drivers.
