BQ28Z610-R1：Does the picture mean that the two hardware parts, BQ28Z610 and BQ28Z610-R1, cannot be used together?Does that mean I want to use the software part of BQ28Z610-R1, must I use the IC of BQ28Z610-R1?

Hello,

The picture you shared outlines the differences from the bq28z610 to the bq28z610-r1. The new revision has just fixed some hardware bugs, you should use the firmware designed for the gauge revision you are using.

Sincerely,

Wyatt Keller
