L298N H-bridge Motor Controller, DROK L298N Motor Driver Board DC Dual H Bridge Robot Stepper Motor Regulator and Drives Module for Arduino Smart Car Power UNO MEGA R3 Mega2560 Duemilanove DROK L298N h-bridge motor controller working mode creates higher working efficiency, L298N as main chip, ST corporation production. Can drive one 2-phase stepper motor, one 4-phase stepper motor or two DC motors. To avoid damage the voltage stabilizing chip, please use an external 5V logic supply when using more than 12V driving voltage. Use large-capacity filter capacitors and diode with freewheeling protection function, increasing reliability. Our motor regulator board drive voltage is 5V-35V, drive current is 2A, max power is 25W. Large capacity filter capacitance, afterflow protection diode, more stable and reliable.
