L298N as main chip, ST corporation production.
Low heat,outstanding anti-interference performance.
High working power to 46v,large current can reach 3A MAX and continue current is 2A, power to 25w.
Can drive one 2-phase stepper motor, one 4-phase stepper motor or two DC motors.
Built-in 78M05,get power from drive power,however, when drive power over12V, please use the external 5v power as power supply.
Large capacity filter capacitance,afterflow protection diode, more stable and reliable.
Specification:
Double H bridge drive
Chip: L298N (ST NEW)
Logical voltage: 5V

Logical current: 0mA-36mA
Drive current: 2A(MAX single bridge)
Max power: 25W
Size:43 x 43 x 26mm
Net weight: 25g
Package weight:36g
Note:
This module has a built-in 5v power supply, when the driving voltage is 7v-35v, this supply is suitable for power supply
DO NOT input voltage to +5v supply interface, however ledding out 5v for external use is available.
When ENA enable IN1 IN2 control OUT1 OUT2
When ENB enable IN3 IN4 control OUT3 OUT4
Note:
1 When you drive voltage (12V input on the map identified as actual acceptable input range is 7-12V) to 7V
-12V, they can enable the onboard 5V logic supply, when using the onboard 5V power supply, the interface of the +5 V
Do not enter the power supply voltage, but it can lead to 5V voltage for external use. (This is the routine application!)
(2) When the drive voltage higher than 12V, less than or equal 24V (chip can support manual presented to 35V, but in accordance with the
298 conservative general inspection applications to 24V maximum voltage support has been very great! Time), for example, to drive a rated voltage of
18V motor. First, you must unplug the onboard 5V output enable jumper cap. Then 5V 5V output port external access
L298N internal logic voltage supply. (This is a high voltage driver unconventional application!)
ST L298N is produced by a high-voltage, high-current motor driver chip. The chip uses 15-pin package. The main features are: high voltage, maximum operating voltage up to 46V; output current, instantaneous peak current up to 3A, continuous operating current of 2A; rated power of 25W. Contains two H-bridge high-voltage and high current full-bridge driver can be used to drive DC motors and stepper motors, relays, coils and other inductive loads; using standard logic level signal control; has two enable control side, in allows the input signal without being affected or prohibit a logic device operating power input, the internal logic circuit part of the work at low voltage; possible external sense resistor, the change in the amount of feedback to the control circuit. Drive motors using L298N chip, the chip can drive a two-phase stepper motors or four-phase stepper motor, can drive two DC motors.
