Its performance has been improved greatly. It can bear larger current due to the increased haetsink dissipation. It is easy to control, using LGS's outstanding high-power motor driver chip, the L298N. This chip allows for direct drive of two bi-directional DC motors, and incorporates high-speed short diodes for protection. Drive current up to 2A per motor output. The driver uses a broad-brush design to reduce wire resistance. Specifications             The logic part of the input voltage: 6 ~ 12V Driven part of the input voltage Vs: 4.8 ~ 46V The logical part of the work current Iss: 36mA Drive part of the operating current Io: 2A Maximum power dissipation: 25W (T = 75 degree Celsius) Control signal input level: High level: 2.3V = Vin = Vss Low:-0.3V = Vin = 1.5V Operating temperature: -25 degree Celsius ~ +130 degree Celsius Drive Type: Dual high-power H-bridge driver Module Size: 47 mm × 53mm Module Weight: About 29g Pin Out DRI0002 Pinout Detailed Descriptions Motor Terminal The terminals are used to connected to the motors, which labeled "+" and "-" representing motor polarity. LED PWM: Power LED Motor Status LED: Motors work normally, thus the lED will light up. Power VD: Power Supply 6.5V~12V; VS: Motor Power Supply 4.8～46V; GND: The common ground of Logic Power Supply and Motor Supply Supply Switching Jumper When jumper is shorted, logic power supply voltage is the same as the motor power supply. If motor power supply is less than 12V，you can set jumper shorted. If motor power supply is more than 12V, dont't short jumper! Motor Control Pins E1,E2: Motor Enable Pin（PWM Control） M1,M2: Motor Signal Pin. Eg: M1 = 0,the motor rotates in forward direction. M1 = 1,the motor rotates in back direction. E M Run LOW LOW/HIGH STOP HIGH HIGH Back Direction HIGH LOW Forward direction PWM LOW/HIGH Speed Note: LOW = 0; HIGH = 1; PWM = 0~255 Tutorial This tutorial shows you how to use l298N motor drive shield to drive two DC motors.
