DRV2605L LRA Driver Flex Module

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.

We just swapped to a 2 layer design. It seems to be very good and we lowered the parts count while making space for the i2c pull-up solder bridge. We might need to redo the pin layout yet again. This still isn't right compared to the other Flex Modules...

Swapped VDD/GND to be consistent with other i2c Flex Modules. Also the font on the bottom has been increased to 4, hopefully it looks better. Still working on a panelization solution for this board.

I have mostly discussed this project on the main Flex Modules project log. I just updated pictures with the new board designs. We are still working to optimize silkscreens and the next batch should be even better.

I got a pretty good flow with hot air, hand solder paste, and hand flux paste placement on the board.  The boards looked great as far as a tented via just a little bigger than the BGA pad and very centered/circular.  I'll now see if they can speak I2C OK or not.
