Inertial navigation peripheral/Sensors
This section will cover the main hardware needed for the peripheral to function, the sensors, micro controller and XO connection.

Hardware choice
Sensors
Our choice of sensors was primarily dictated by cost. We needed at least two sensors, a gyroscope to measure angular velocity, and an accelerometer for tangential acceleration. Initially we were planning to have pitch and roll compensation for the device, but this was shoved towards the end.
For the accelerometer, we got a Triple Axis Accelerometer Breakout - ADXL330 from Sparkfun for $34.95 and for the gyroscope, we got a Gyro Breakout Board - Dual Axis IDG300 for $74.95, also from Sparkfun. Hypothetically, we could get cheaper sensors in the future, as we only ended up using one axis of the gyroscope and accelerometer.
