Using a Nano as an extension to a flight controller

No, this is an Adafruit LSM9DS1 breakout board, with several sensors on it.
It is out of stock.
It would be neat if I could get it.

I can buy just an Adafruit accelerometer, MMA8451.
What do you think? - I suppose Adafruit have info on how to hook it up, and how to use it.
