Can You Help Check if the Wiring Between the Driver and Raspberry Pi Is Correct on a PCB I am Designing?

Our core responsibility is to ensure the provided component parameters are accurate and their performance is reliable. However, as circuit system design involves overall solution matching (such as controller characteristics, application scenarios, etc.), we are unable to provide comprehensive wiring or PCB design guidance. Thank you for your understanding.

Regarding key points during the connection process, we can offer some basic tips for your reference:

1. Positive/Negative Pin Connections: Strictly adhere to the "Power Pin Definition" and "Signal Level Range" specified in the driver manual.
2. ALM and Other Outputs: Such outputs require external pull-up resistors to form valid level signals, and signal direction must be noted – ALM, as an "output signal" from the driver, should be connected to an "input pin" on the controller.
3. ENA and Other Control Signals: Confirm the driver's logic requirements for control signals (e.g., active high/low) and ensure they match the controller's output characteristics (e.g., voltage, drive capability) to avoid signal conflicts.

For final verification of circuit correctness, it is recommended to carefully cross-check against the "Electrical Interface Specifications" in the complete driver manual. If necessary, consult professional circuit design personnel to ensure the PCB design meets your application requirements.
