L298N Motor Drive Board Module DC Stepper Motor Robot Smart Car Double H Bridge
[4000262475641] modname=ckeditor program book: http://wenku.baidu.com/view/bb2431ed941ea76e58fa04f7.html Double H bridge motor drive module Operating mode: h-bridge drive (two-way) Main control chip: L298N Logical voltage: 5V Driving voltage: 5v-35v Logic current: 0ma-36ma Driving current: 2A(MAX single bridge) Storage temperature: -20℃ to +135℃ Maximum power: 25W Weight: 30 g Peripheral dimension: 43*43*27mm Product features: ★ this module USES ST company's L298N as the main driver chip, with strong driving ability, low calorific value, strong anti-interference ability. ★ this module can use the built-in 78M05 power through the drive power supply part to work, but in order to avoid the damage of voltage stabilizing chip, when using more than 12V drive voltage, please use the external 5V logic power supply. ★ this module USES a large capacity filter capacitor, secondary protection diode, can improve the reliability. Application scope of driver module L298N is a high voltage, large current motor driver chip produced by ST company.The chip adopts 15-pin package.The main characteristics are: high working voltage, the highest working voltage up to 46V;The output current is large, the instantaneous peak current can reach 3A, and the continuous working current is 2A.Rated power 25W.Full-bridge driver with high voltage and large current with two H Bridges can be used to drive inductive loads such as dc motor, stepping motor and relay coil.Standard logic level signal control is adopted.There are two enable control terminals, which allow or disable the device to work without being affected by the input signal. There is a logical power supply input terminal, which enables the internal logic circuit part to work at low voltage.External detection resistance can be connected, the change will be fed back to the control circuit.The L298N chip is used to drive the motor, which can drive either a two-phase stepping motor or a four-phase stepping motor, or two dc motors. This module integrates a built-in 5V power supply.When your drive voltage is 7v-35v, you can power the onboard 5V logic. When using the onboard 5V power supply, the +5V power supply in the interface does not input the voltage, but can lead out the 5V voltage for external use When ENA enables IN1 IN2 control OUT1 OUT2 When ENB enables IN3 IN4 control OUT3 OUT4
