ufadv.blogg.se - L298n motor driver not working

We can control the stepping motor through two pins of the controller, one controls the rotation direction and the other controls the number of steps.Ī4988 provides five different microstep controls: Get MDV 2x2A DC Motor Controller (L298N) from DFRobot Store or DFRobot Distributor.A4988 has built-in decoder. They should share the GND pins.ĪnalogWrite(E1, value) //PWM Speed ControlĪnalogWrite(E2, value) //PWM Speed Controlįor any questions, advice or cool ideas to share, please visit the DFRobot Forum.

# Note: You should connect the GND pin from the DF-MD v1.3 to your MCU controller. # Motor B -> Screw terminal close to E2 driver pin

# Motor A -> Screw terminal close to E1 driver pin # Motor Power Supply -> Centor blue screw connector(5.08mm 3p connector) # The sketch for using the motor driver L298N # Product name: L298N motor driver module DF-MD v1.3 Sample Code // # Editor : Lauren from DFRobot This tutorial shows you how to use l298N motor drive shield to drive two DC motors. Note: LOW = 0 HIGH = 1 PWM = 0~255 Tutorial M1 = 1,the motor rotates in back direction. Eg: M1 = 0,the motor rotates in forward direction. If motor power supply is more than 12V, dont't short jumper! Motor Control Pins If motor power supply is less than 12V，you can set jumper shorted. When jumper is shorted, logic power supply voltage is the same as the motor power supply.

GND: The common ground of Logic Power Supply and Motor Supply.

Motor Status LED: Motors work normally, thus the lED will light up.

The terminals are used to connected to the motors, which labeled "+" and "-" representing motor polarity.

Drive Type: Dual high-power H-bridge driver.

Operating temperature: -25 degree Celsius ~ +130 degree Celsius.

Maximum power dissipation: 25W (T = 75 degree Celsius).

Drive part of the operating current Io: 2A.

The logical part of the work current Iss: 36mA.

Driven part of the input voltage Vs: 4.8 ~ 46V.

The logic part of the input voltage: 6 ~ 12V.

The driver uses a broad-brush design to reduce wire resistance. This chip allows for direct drive of two bi-directional DC motors, and incorporates high-speed short diodes for protection. It is easy to control, using LGS's outstanding high-power motor driver chip, the L298N. It can bear larger current due to the increased haetsink dissipation. Its performance has been improved greatly. This is a 4.8-46V, 2A Dual Motor Controller which is the revised version of the DF-MDV1.0.
