Difference between SX1509 V1 and V2 boards?

Qwiic System

I have several SX1509 Qwicc breakouts of unknown vintage. The current ordering page says it’s for the “V2” breakout, but there’s nothing about what changed between V1 and V2. There’s no version info in the breakout that I can see.

So, what is the difference?

The board layout was different : GitHub - sparkfun/SparkFun_SX1509_Arduino_Library at V_1.0.0

Sometimes the board layout gets changed to make a board easier to manufacture.
