The whole architecture is like this.
##1. Connect Motor drivers and Arduino
Pin names of the motor driver are like below.
Connect Arduino and motor driver as the table below.
| Arduino Pin | Motor Driver number | Motor Driver Pin |
|---|---|---|
| 3 | 1 | 1PWM |
| 2 | 1 | 1INA |
| 4 | 1 | 1INB |
| 5 | 1 | 2PWM |
| 7 | 1 | 2INA |
| 8 | 1 | 2INB |
| Arduino Pin | Motor Driver number | Motor Driver Pin |
|---|---|---|
| 6 | 2 | 1PWM |
| 12 | 2 | 1INA |
| 13 | 2 | 1INB |
| 9 | 2 | 2PWM |
| A5 | 2 | 2INA |
| A4 | 2 | 2INB |
| Arduino Pin | Motor Driver number | Motor Driver Pin |
|---|---|---|
| 10 | 3 | 1PWM |
| A3 | 3 | 1INA |
| A2 | 3 | 1INB |
| 11 | 3 | 2PWM |
| A1 | 3 | 2INA |
| A0 | 3 | 2INB |
It would be like this.
The gpio pin header is like this.
Connect 5V battery to this DC Power 5V and Ground
Reference: How do I power my Raspberry Pi?
Before connection, it would be like this.
After connection, if would be like this.
