At some point in the future I'll be switching pins again. The i2c was always laid out different from the other Flex Modules. This R 2.0 version will flip the DRV2605 and that allowed me to fix this. I have about 2 dozen R1.0-1.1 LRA Haptic Flex Modules to sell before they are made and I'll keep the documentation referencing them and add the new design info when the R2 are ready.
