The motor terminals connect to Motor Terminals 1, 2, 3, 4. You have Motor A inputs and Motor B inputs. This means the +5V terminal is not for powering the board but for connecting a device, say Arduino, that needs a 5V source. When the +12V jumper is attached, the on-board voltage regulator is now enabled, and you can source +5V from the +5V terminal. Important note: remove the +12V jumper shown if you are using powers higher than +12V. More information about the L298N IC is found on its datasheet: This means you can power high voltage motors while controlling them with microcontrollers. The most notable feature here is its high power supply although its input pins follow lower voltage levels. The diagram above shows an example diagram for using the L298N to drive one DC motor. To drive the motor counter clockwise, the pin Input 1 is low while the pin Input 2 is high. To drive a motor to a direction, say, clockwise, the pin Input 1 must be high while the pin Input 2 must be low. The Enable A pin must be high to turn on the motor. For example, if a motor is using channel A, its terminals must be connected to pins Out 1 and Out 2.

This IC drives two motors through two channels, A and B. It comes in two IC packages: MultiWatt15 and PowerSO20. The L298N is an integrated circuit that follows the H-bridge concept. This is very significant especially when using an Arduino board where the 5V power source is simply not enough for two DC motors. etc characteristic, the most important thing is to realize the complete electrical isolation between input port and output port.The other benefit of using an H-bridge is that you can provide a separate power supply to the motors. In addition, this module adopt a TLP280-4 optical coupler, which has strong anti-jamming ability、work stability、long service life and higher transmission efficiency. Different stepper motor may have different connection. One of phase coil of the dual phase stepper motor is connected to M1A and M1B, another phase coil is connected to the M2A and M2B. Stepper motor module working voltage range: DC 8.0-35V. Low speed for fast attenuation will lead to serious motor weakness, if very serious then will appear the phenomenon of positioning is not exact. When high speed for slow attenuation will appear vibration with high noise. High speed for fast attenuation, low speed for slow attenuation. If PFD input voltage is higher than 0.6 VDD, then choose slow attenuation mode if Less than 0.21 VDD, then choose fast attenuation mode If between the two mode, then choose mixed attenuation mode.ĭifferent speed of the motor should choose different attenuation mode.

Please adjust the voltage of PFD through R4, which is to control the current attenuation mode. More current means a strong drive ability and more power consumption and emit more heat. When clockwise rotation R5, the current increase. The user can change the size of the current of stepper motor by changing the size of R5 resistance. Please adjust the precision of the stepper motor through the switch 1 and switch 2 as follows: About the stepper motor output, One of phase coil of the dual phase stepper motor is connected to M1A and M1B, another phase coil is connected to the M2A and M2B. Second: The input interface contains reset control and other three way control signal. The main controller chipset for stepper motor module V1.0 is A3977.įirst: Connect with external power supply through V01 interface, the input voltage of this module should be between 8.0V and 35V. We can control the amount of angular displacement through controlling the number of pulses, so as to achieve accurate positioning purposes at the same time we can also control the speed rotation and acceleration of the motor through controlling the pulse frequency, then to achieve speed adjustment. Under non-overload conditions, the motor speed, the stop position only depends on the frequency and number of pulses of the pulse signal, and regardless of load changes, its rotation is operated in a fixed angle step by step. The stepper motor is the open loop control element that can change the electrical pulse signal into angular displacement or linear displacement.
