L298N Motor Drive Controller Board Module Dual H Bridge DC Stepper For Arduino (1)

Dual-channel H-bridge driver working mode creates higher working efficiency,L298N as main chip. 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 35v,large current can reach 3A MAX and continue current is 2A, power to 25w. Large capacity filter capacitance ,after flow protection diode, more stable and reliable. This module has a built-in 5v power supply, when the driving voltage is 7v-35v, this supply is suitable for power supply When ENA enable IN1 IN2 control OUT1 OUT2 Specification: Chip: ST L298N dual H-bridge driver chip Logic voltage: 5V Logic current 0mA-36mA Storage Temperature: -20 ¡æ to +135 ¡æ Operating mode: H-bridge driver (dual) Drive voltage: 5V-35V Drive current: 2A (MAX single bridge) Maximum power: 25W Driver Board Size：55mm*60mm*30mm Driver Board Weight:33g Dimensions: 43x43x27mm Note: General Application: When your driver is 7V-12V, you can enable the on-board 5V logic supply. When using the on-board 5V power supply, the + 5V power supply in the interface does not input voltage, but it can draw 5V voltage for external use. Unconventional application of high-voltage drive: When the driving voltage is higher than 12V, less than or equal to 24V, for example, to drive a motor with rated voltage of 18V, the jumper cap with 5V output enabled on-board voltage must be pulled out and then outside the 5V output port Connect 5V voltage to L298N internal logic voltage supply. There are two ways to turn the system back on: 1. flip the power switch on the back of the computer and wait for the power supply cap to discharge as the relay will reset without power. 2.after popping the hood and examining for faults, press the button on the relay. There is a red LED on this for power and a green LED to indicate the relay is activated, so you can be pretty sure what state this is in . Any time you are trying to hot wire an ATX power supply and you need a toggle function besides the switch in the back, just needs power from pin 9, the relay connected to pin 16 and then of course connections back to ground pin(s).
