Specification: 

Chip: L298N 

Logic voltage: 5V 

Logic current 0mA-36mA 

Maximum power: 25W 

Drive voltage: 5V-35V 

Drive current: 2A(For each DC motor) 

Operating mode: Dual H-bridge driver (can drive 2 DC motors) 

Reason 1: Use L298N for Main Chip 

Application: 

When your driver is 7V-12V, you can enable the on-board 5V logic supply. When using the on-board 5V power supply, 

the + 5V power supply in the interface does not input voltage, but it can draw 5V voltage for external use.
