Controlled via a 74HCT594 shift register to save Arduino pins.
If the "PWR" jumper is connected, the shield draws power from the Arduino. For high-torque motors, remove the jumper and use the EXT_PWR terminals. hw 130 motor control shield for arduino datasheet
Precise speed control (the L298N has a non-linear response) or high-torque motors (get a MOSFET-based shield like the Adafruit Motor Shield v2). Controlled via a 74HCT594 shift register to save
These are the screw terminals for DC motors. Stepper 1: Uses M1 and M2. Stepper 2: Uses M3 and M4. hw 130 motor control shield for arduino datasheet
