Honbay L298N Motor Drive Controller Board DC Dual H-Bridge Robot Stepper Motor Control & Drives Module for Arduino Smart Car Power UNO MEGA R3 Mega2560 Duemilanove Nano Robo L298N has such characteristics as strong driving ability, low calorific value and strong anti-interference ability L298N as main driver chip makes strong driving ability/small heating/strong Dual-channel H-bridge driver working mode creates higher working efficiency Using large capacity filter capacitor, this module can follow current to protect diodes, and improve the reliability This module can use built-in 78M05 for electric work via a driving power supply part. But to avoid the damage of the voltage stabilizing chip, please use an external 5V logic supply when using more than 12V driving voltage
