4.5V to 25V (though some versions specify up to 12V or 16V depending on capacitor ratings). Protection: Internal kickback diodes and thermal shutdown. 5.imimg.com Pinout and Connectivity
The HW 130 is often mistakenly labeled as simply an "L298N module." However, the HW 130 variant includes specific onboard voltage regulation and pin mapping optimized for the Arduino form factor. hw 130 motor control shield for arduino datasheet
