L298N as main chip, ST corporation production.low heat,outstanding anti-interference performance.high working power to 46v,large current can reach 3A MAX and continue current is 2A, power to 25w. can drive one 2-phase stepper motor, one 4-phase stepper motor or two DC motors.
Logical voltage 5V
Drive voltage 5V-35V
Output current: rated current 2A, maximum 3A (need to add heat sink), if the output power greater than 15W, combined heat sink is proposed.
Drive current 2A(MAX single bridge)
Size：（Long）42mm *（wide1）42 mm *（high）28mm
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
