Intelligent Vehicle - DRV8701 Dual-Drive Open Source

Schematic diagram: The motor test is shown in the video; it can be used in both left and right directions, and also in reverse.
The DRV8701 can operate within a wide voltage range of 6-45V without external boost. One DRV8701E chip can drive multiple H-bridges.
The DRV8701E, in conjunction with an H-bridge circuit, is used to drive DC motors. Its working principle is to control the motor's speed (PWM) and direction (high and low levels) by controlling the input signal. It provides the current and voltage required for motor drive while protecting the motor from damage such as overcurrent, overvoltage, and short circuits. The DRV8701E also has several protection functions, such as overcurrent protection, overheat protection, and undervoltage protection, to ensure the safe operation of the motor and driver.
It can be used in intelligent car competitions (PCB layout modification required), electronic competitions, and other competitions for driving DC motors.
Advantages of this open-source project:
1. Small size.
2. Stable; it has been used for 1 year and 3 months and is still in use without damage. (No wiring errors, no damage, and no limit testing were performed during use).
3. The circuit can still work normally after the motor stalls.
4. The signal input section is isolated from the ground plane return current.
