L298N Motor Driver Board Module Stepper Motor Smart Car Robot Breadboard Features: Good quality: L298N as main chip, with strong driving ability, low heat and strong anti-interference ability Application: To avoid damage the voltage stabilizing chip, please use an external 5V logic supply when using more than 12V driving voltage Good performance: Use large-capacity filter capacitors and diode with freewheeling protection function, increasing reliability Specification: Logical voltage : 5V Drive voltage : 5v-35V Logical current : 0mA-36mA Driving current : 2A(MAX single bridge) Storage temperature : - 20 to + 135 Maximum power: 25W Size: 43*43*27mm Color: multicolor Material: electronic components Warm tips: When you are driving voltage (above logo for the 12 v input, can actually accept input range is 7 to 12 v) for 7 v to 12 v, can make to onboard power supply 5 v logic, when using the onboard after 5 v power supply, interface of + 5 v The power supply does not input voltage, but can yield 5V voltage for external use. When the driving voltage is higher than 12V, it is less than or equal to 24V (the chip manual proposes to support 35V, but according to the book When the maximum voltage is applied to the maximum voltage of 298 conservative applications to 24V, for example, the motor with a rated voltage of 18V shall be driven. You must first remove the board 5V output to enable the jumper cap. Then 5V is accessed outside the 5V output port The 5V enables the power to be a control signal with a level of 5V. When the signal input is valid, and when the power supply is normal in the motor drive module, the motor drive module outputs the current. Otherwise, even if the power supply is normal, there is no current on the motor. _x000D_
