L298N motor drive module

Since I haven’t learned much in my freshman year, I drew the first module I came into contact with, L298N.
In the PCB of this project, an area is reserved after L298N for welding the heat sink. To weld the heat sink, you need to add the pad at the corresponding position. The diodes are distributed on both sides for easy soldering (if you use a soldering iron, you can increase the spacing between adjacent diodes appropriately). Because this module is a motor drive module, the power lines need to be widened, so the "filling area" in Jialichuang is used to lay copper connections between the power pins, and the signal lines are connected using wires. After connecting the PCB, you can add some vias near some components that easily generate heat to dissipate heat.

After welding, the actual product can be used, which can drive the forward and reverse rotation of the motor and complete PWM speed regulation.
