L298N Dual H Bridge DC Motor Driver Stepper Motor dual channel for Arduino

Low heat, outstanding anti-interference performance.
High working power to 46V, large current can reach 3A maximum and continuous current is 2A, power to 25W. 
Can drive one 2-phase stepper motor, one 4-phase stepper motor or two DC motors.
Built-in 78M05, get power from drive power; however, when drive power is over 12V, please use the external 5V power supply.
Large capacity filter capacitance, afterflow protection diode, more stable and reliable.

Specification:
Double H bridge drive
Chip: L298N (ST NEW)
Logical voltage: 5V
Drive voltage: 5V-35V
Logical current: 0mA-36mA

Net weight: 26g
Package weight: 36g

Periphery dimension: 43 x 43 x 27mm (L x W x H)
Note:
This module has a built-in 5V power supply; when the driving voltage is 7V-35V, this supply is suitable for the power supply.
Do not input voltage to the +5V supply interface; however, leading out 5V for external use is available.
When ENA is enabled, IN1 IN2 control OUT1 OUT2.
When ENB is enabled, IN3 IN4 control OUT3 OUT4.
