Product Description

Details

Features

  • Use an L298N by ST as the driver chip which is powerful in drive, low heat and high anti-interference performance
  • Adopt a high-capacity filter capacitor and a freewheeling diode that protects devices in the circuit from being damaged by the reverse current of an inductive load, enhancing reliability
  • The module can utilize the built-in stabilivolt tube 78M05 to obtain 5v from the power supply. But to protect the chip of the 78M05 from damage, when the drive voltage is greater than 12v, an external 5v logic supply should be used.
  • Drive voltage: 5-35V; logic voltage: 5V
  • PCB size: 4.2 x 4.2 cm. For more info, please refer to http://wiki.sunfounder.cc/index.php?title=Motor_Driver_Module-L298N

Introduction
The L298 is a high voltage and high current dual full-bridge drive in a 15-lead Multiwatt and PowerSO20 packages. It features: high operating supply voltage up to 46V; large DC current, peak instantaneous current up to 3A, continuous operating current as 2A; rate power: 25W. 
It has two H-bridge drives to drive inductive loads such as relays, solenoids, DC and stepping motors. It uses the standard logic level signals for control. Two enable inputs are provided to enable or disable the device independently of the input signals. A logic power input is added so the internal logic circuit can work under a lower voltage. An external sensor resistor can be connected to provide the variation to the control circuit. 
The L298N chip can drive a two-phase or four-phase stepping motors, or two DC motors. 

Application 
The module can be applied to: 
-Drive DC motors. Since the module uses a dual H-bridge drive, it can drive two motors at the same time. 
-Drive stepping motors. It can also drive two stepping motors synchronously. 

Component List
1 * Motor Drive-L298N module

Note: 

When the drive voltage is 7V – 12V, you may use the on-board 5V for power supply and do not need to use the 5V pin. Instead you can use the 5V pin output as power for external devices. This is the normal application way for the module.

Schrittmotor-Treiber L298N By Pilu 2016-07-04 17:03:33

Preisgünstiger Treiber mit 5V-Konstantspannungsregler (5V-Klemme z.B. zur Versorgung einer externen Ansteuerschaltung). Die vier 5V-Ansteuereingänge sind auf LEDs geführt (Ansteuerung erfolgte bei mir über eine CMOS-Logik). Enable über Jumper schaltbar.
Zwar liegen keine Anschlußunterlagen bei, jedoch leicht durchschaubar, deshalb volle Punktezahl.

The little LM298 motor controller chip is capable of handling up to 2 amps load with the heavy duty heat sink on board (possibly a bit more if you install a small fan). This board is easy to use, durable and it works with out a hitch of the designed load By Mike3746 2016-05-19 13:48:05

Excellent device, easy to sue and it is versatile with the enable contacts jumped to ground. You can start-stop-reverse the motors at full speed with the jumpers in place, or remove the jumpers clips and use enable with PWM (pulse width modulation) to control speed. This can save wiring for you is you don't need to control speed, as may be the case with geared motors moving objects at set stepped as in the case with a wench or elevator or single pulse controlled jack levers. The contacts are soldered in very nicely so they are solid and durable
