MinIMU-9 v3 Gyro, Accelerometer, and Compass (L3GD20H and LSM303D Carrier) https://www.pololu.com/product/2468
A minimum of four connections are necessary to use the MinIMU-9: VIN, GND, SCL, and SDA.
VIN should be connected to a 2.5 V to 5.5 V source GND to 0 volts,
SCL and SDA should be connected to an I²C bus operating at the same logic level as VIN.
(Alternatively, if you are using the board with a 3.3 V system, you can leave VIN disconnected and bypass the built-in regulator by connecting 3.3 V directly to VDD.)

where do we go? p23 what are CTRL9_XL CTRL_1_XL CTRL_10_C CTRL2_G
p8. what are the units? what are the rest of these names?
where do we get the scale? [pulled from arduino code from manufacturer’s site.]
