	Properties
	Output Data Rate
Specifies the gryoscope sample data rate
	Full Scale Selection
Specifies the maximum angular speed which the sensor can measure in degrees per second
	Bandwidth Selection
Linked with data rate, See device datasheet table 21.
	Filter Enable
Enables automatic internal filtering on the gyro data
	X Axis
Enables or disables the selected axis allowing it to generate data or be switched off to save power.
	Y Axis
Enables or disables the selected axis allowing it to generate data or be switched off to save power.
	Z Axis
Enables or disables the selected axis allowing it to generate data or be switched off to save power.
	Connection
	Address Pin
The state of the SDO address pin. 0 = Connected to GND 1 = Connected to VCC
	Channel
Channel selection
	SDA
Pin used for SDA (data signal)
	SCL
Pin used for SCL (clock signal)
	Baud Select
Baud rate option selector
	Baud Rate
Baud rate to be used
	Stop Delay
On older microcontroller devices there is a potential for the I2C hardware channel to lock up if there is not a 10ms delay between an I2C stop event and the next I2C start event. Most modern microcontrollers will not have a problem so this property can be disabled to speed up the I2C communications.
	Simulation
	Label

	Simulate Comms
Controls where the simulation data comes from. Component GUI - Data comes from the sliders on the component panel GUI API - Comms data is sent and received via an API component
