DRV2604: [urgent]Please let me know the position of the first pin in the actual sample.

Hi,

Welcome to E2E and thank you for your interest in our products!

The first pin in the sample that you shared is located where the point marker is placed in the picture of the left. The Ball A1 corner would be located in the right upper corner in that picture.

For more information about the balls locations, please take a look at the package outline information from the datasheet.
