L298N main chip. Low heat, maximum performance. High power 46 V, maximum current can reach 3A, can operate at 2A and up to 25 V. Can control a two-stage engine or a four-stage engine. It can also work directly with two engines of the same stage, direct current. The built-in 78M05 power supply unit receives power from the drive power, however, if the drive power is more than 12 volts, an external 5 volt power supply should be used as a power source.
Note: This module has a built-in 5 volt power supply. When the voltage is 7 V-35 V, the built-in unit is not suitable for power supply; therefore, use an external power supply unit so as not to damage the module
