The HW-130 motor control shield is a popular choice among Arduino enthusiasts, but there are other shields available with similar features. Some examples include: void setup() Serial

The HW-130 is built around two chips and a 74HC595 shift register to minimize the number of Arduino pins used. Specification Motor Driver Chip 2 x L293D Operating Voltage 4.5V to 25V DC (Motor Supply) Output Current 0.6A per channel (1.2A Peak) DC Motor Support Up to 4 bi-directional motors Stepper Support Up to 2 stepper motors (Unipolar or Bipolar) Servo Support 2 dedicated 5V hobby servo headers Protection Thermal shutdown and internal kickback diodes Understanding the Pinout & Layout If you use analogWrite() on pins 9, 10,

For more details, you can refer to the L293D Based Arduino Motor Shield Datasheet or the Adafruit Motor Shield V1 Guide .

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.
