This is a 4.8-46V, 2A Dual Motor Controller which is the revised version of the DF-MDV1.0. 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.

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

NOTE: Ensure you have a ground wire running between Arduino GND and motor controller GND where battery power GND is connected.

// # Product name: L298N motor driver module DF-MD v1.3
// # Product SKU : DRI0002
// # Version     : 1.0
 
// # Description:
// # The sketch for using the motor driver L298N
// # Run with the PWM mode
 
// # Connection:
// #        M1 pin  -> Digital pin 4
// #        E1 pin  -> Digital pin 5
// #        M2 pin  -> Digital pin 7
// #        E2 pin  -> Digital pin 6
// #        Motor Power Supply -> Centor blue screw connector(5.08mm 3p connector)
// #        Motor A  ->  Screw terminal close to E1 driver pin
// #        Motor B  ->  Screw terminal close to E2 driver pin
// # 
// # Note: You should connect the GND pin from the DF-MD v1.3 to your MCU controller. They should share the GND pins.
