Qunqi L298N Motor Drive Controller Board Module Dual H Bridge DC Stepper For Arduino Dual-channel H-bridge driver 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 High working power to 46v,large current can reach 3A MAX and continue current is 2A, power to 25w. Large capacity filter capacitance,afterflow protection diode, more stable and reliable. Chip: L298N Logic voltage: 5V Logic current 0mA-36mA Storage Temperature: -20  to  to +135 Operating mode: H-bridge driver (dual) Drive voltage: 5V-35V Drive current: 2A (MAX single bridge) Maximum power: 25W Dimensions: 43x43x27mm This module has a built-in 5v power supply, when the driving voltage is 7v-35v, this supply is suitable for power supply DO NOT input voltage to +5v supply interface, however ledding out 5v for external use is available. When ENA enable IN1 IN2 control OUT1 OUT2 When ENB enable IN3 IN4 control OUT3 OUT4 1x L298N Module
