Function description:
1. This motor drive module uses the dual full-bridge drive chip L298N as the core to meet the motor drive requirements of higher voltage and larger current.
2. Integrated optional 5V voltage stabilizing circuit, motor drive port protection circuit, working status indicator light, motor current test port, rich functional interfaces, etc.
Precautions:
1. The DC current of L298N can reach 4A, so the power cord should meet the requirements of 4A. 35um: 1.5mm-3.2A current 2mm-4A current 50um: 1.5mm-3.5A current 2mm-4.3A current 70um: 1.5mm-4.2A Current 2mm-5.1A current so: the total power line width should be 2mm
2. The 104 capacitor should be as close to the chip as possible
3. The 220uF electrolytic capacitor should be the current outlet
