Adafruit DS3231 Precision RTC FeatherWing
This is the DS3231 Precision RTC FeatherWing: it adds an extremely accurate I2C-integrated Real Time Clock (RTC) with a Temperature Compensated Crystal Oscillator to any Feather main board. This RTC is the most precise you can get in a small, low power package. Most RTCs use an external 32kHz timing crystal that is used to keep time with low current draw. And that’s all well and good, but those crystals have slight drift, particularly when the temperature changes (the temperature changes the oscillation frequency very very very slightly but it does add up!) This RTC is in a beefy package because the crystal is inside the chip! And right next to the integrated crystal is a temperature sensor. That sensor compensates for the frequency changes by adding or removing clock ticks so that the timekeeping stays on schedule. With a CR1220 12mm coin cell plugged into the top of the FeatherWing, you can get years of precision timekeeping, even when main power is lost. Great for datalogging and clocks, or anything where you need to really know the time.

EEPROM
EEPROM (Electrically Erasable Programmable Read-only Memory) is a type of non-volatile memory. EEPROM is a type of non-volatile ROM that enables individual bytes of data to be erased and reprogrammed. That is why EEPROM chips are known as byte erasable chips. EEPROM is usually used to store small amounts of data in computing and other electronic devices. It is used in computers, usually integrated in microcontrollers such as smart cards and remote keyless systems, or as a separate chip device, to store relatively small amounts of data by allowing individual bytes to be erased and reprogrammed.
The microcontroller on the Arduino boards have 512 bytes of EEPROM: memory whose values are kept when the board is turned off. Functions in the EEPROM class are automatically included with the platform for your board, meaning you do not need to install any external libraries. The supported microcontrollers on the various Arduino have different amounts of EEPROM: 1024 bytes on the ATmega328P, 512 bytes on the ATmega168 and ATmega8, 4 KB (4096 bytes) on the ATmega1280 and ATmega2560. The Arduino boards have an emulated EEPROM space of 1024 bytes. The EEPROM library on ESP32 provides a reliable way to store data persistently, so that it remains accessible even when the power supply is disconnected. Unlike RAM, the data we save with the EEPROM library does not get lost when power is cut. This feature makes it an ideal choice for retaining configurations, settings, and other important data in embedded devices like the ESP32.

Quaternion
In mathematics, the quaternion number system extends the complex numbers. Quaternions were first described by the Irish mathematician William Rowan Hamilton in 1843 and applied to mechanics in three-dimensional space. Hamilton defined a quaternion as the quotient of two directed lines in a three-dimensional space, as the quotient of two vectors. Multiplication of quaternions is noncommutative.
Quaternions are used in pure mathematics, but also have practical uses in applied mathematics, particularly for calculations involving three-dimensional rotations, such as in three-dimensional computer graphics, computer vision, and crystallographic texture analysis. They can be used alongside other methods of rotation, such as Euler angles and rotation matrices, or as an alternative to them, depending on the application.
SparkFun 9 Degrees of Freedom Breakout – MPU-9150
The SparkFun 9DOF MPU-9150 is the world’s first 9-axis MotionTracking MEMS device designed for the low power, low cost, and high performance requirements of consumer electronics equipment including smartphones, tablets and wearable sensors. And guess what? You get to play with it.
This breakout board makes it easy to prototype with the InvenSense MPU-9150 by breaking out all the pins you need to standard 0.1″ spaced headers. The board also provides I2C pullup resistors and a solder jumper to switch the I2C address of the device.
The MPU-9150 is a System in Package (SiP) that combines two chips: the MPU-6050, which contains a 3-axis gyroscope, 3-axis accelerometer, and an onboard Digital Motion Processor™ (DMP™) capable of processing complex MotionFusion algorithms; and the AK8975, a 3-axis digital compass. The part’s integrated 6-axis MotionFusion algorithms access all internal sensors to gather a full set of sensor data.

Inertial Measurement Unit
An inertial measurement unit (IMU) is an electronic device that measures and reports a body’s specific force, angular rate, and sometimes the orientation of the body, using a combination of accelerometers, gyroscopes, and sometimes magnetometers. When the magnetometer is included, IMUs are referred to as IMMUs. IMUs are typically used to maneuver modern vehicles including motorcycles, missiles, aircraft, including unmanned aerial vehicles, among many others, and spacecraft, including satellites and landers. Recent developments allow for the production of IMU-enabled GPS devices. An IMU allows a GPS receiver to work when GPS-signals are unavailable, such as in tunnels, inside buildings, or when electronic interference is present.
AltIMU-10 v5 Gyro, Accelerometer, Compass, and Altimeter (LSM6DS33, LIS3MDL, and LPS25H Carrier)
The Pololu AltIMU-10 v5 is an inertial measurement unit (IMU) and altimeter that features the same LSM6DS33 gyro and accelerometer and LIS3MDL magnetometer as the MinIMU-9 v5, and adds an LPS25H digital barometer. An I²C interface accesses ten independent pressure, rotation, acceleration, and magnetic measurements that can be used to calculate the sensor’s altitude and absolute orientation. The board operates from 2.5 to 5.5 V and has a 0.1″ pin spacing.

Roll, Pitch, and Yaw
How is Controlling an Airplane or Robotic Different than Controlling a Car or Boat?
Stability and control are much more complex for an airplane, which can move freely in three dimensions, than for cars or boats, which only move in two. A change in any one of the three types of motion affects the other two.
Imagine three lines running through an airplane and intersecting at right angles at the airplane’s center of gravity.
- Rotation around the front-to-back axis is called Roll.
- Rotation around the side-to-side axis is called Pitch.
- Rotation around the vertical axis is called Yaw.
SparkFun 9 Degrees of Freedom – Sensor Stick
The SparkFun 9DOF Sensor Stick is a very small sensor board with 9 degrees of freedom. It includes the ADXL345 accelerometer, the HMC5883L magnetometer, and the ITG-3200 MEMS gyro. The “Stick” has a simple I2C interface and a mounting hole for attaching it to your project. Also, the board is a mere allowing it to be easily mounted in just about any application.

Gyroscope
A gyroscope is a device used for measuring or maintaining orientation and angular velocity.It is a spinning wheel or disc in which the axis of rotation is free to assume any orientation by itself. When rotating, the orientation of this axis is unaffected by tilting or rotation of the mounting, according to the conservation of angular momentum.
Gyroscopes based on other operating principles also exist, such as the microchip-packaged MEMS gyroscopes found in electronic devices, solid-state ring lasers, fibre optic gyroscopes, and the extremely sensitive quantum gyroscope. MEMS gyroscopes are popular in some consumer electronics, such as smartphones.
SparkFun Tri-Axis Gyro Breakout – L3G4200D
This is a breakout board for the L3G4200D low-power three-axis angular rate sensor. The L3G4200D is a MEMS motion sensor and has a full scale of ±250 or ±500 or ±2000 dps and is capable of measuring rates with a user selectable bandwidth. These work great in gaming and virtual reality input devices, GPS navigation systems and robotics.

Accelerometer
An accelerometer is a tool that measures proper acceleration. Proper acceleration is the acceleration of a body in its own instantaneous rest frame, this is different from coordinate acceleration, which is acceleration in a fixed coordinate system. For example, an accelerometer at rest on the surface of the Earth will measure an acceleration due to Earth’s gravity, straight upwards 9.81 m/s2. By contrast, accelerometers in free fall, falling toward the center of the Earth at a rate of about 9.81 m/s2, will measure zero.
Accelerometers have many uses in industry and science. Highly sensitive accelerometers are used in inertial navigation systems for aircraft and missiles. Vibration in rotating machines is monitored by accelerometers. They are used in tablet computers and digital cameras so that images on screens are always displayed upright. In unmanned aerial vehicles, accelerometers help to stabilise flight. Micromachined microelectromechanical systems accelerometers are increasingly present in portable electronic devices and video-game controllers, to detect changes in the positions of these devices.
SparkFun Triple Axis Accelerometer Breakout – ADXL335
Breakout board for the 3 axis ADXL335 from Analog Devices. This is the latest in a long, proven line of analog sensors, the holy grail of accelerometers. The ADXL335 is a triple axis MEMS accelerometer with extremely low noise and power consumption, only 320uA. The sensor has a full sensing range of +/-3g. There is no on-board regulation, provided power should be between 1.8 and 3.6VDC. Board comes fully assembled and tested with external components installed. The included 0.1uF capacitors set the bandwidth of each axis to 50Hz.

Movement
Accelerometers, gyroscopes, and magnetometers are the three main sensors we use for detecting motion and orientation. We can sense motion with an accelerometer.
Accelerometers are used to measure acceleration, that means linear motion in X, Y or Z. They can be used to detect when they are being moved around, detect motion, shock or vibration. They can also be used to detect gravitational pull in order to detect orientation or tilt.
Gyroscopes are used to measure rotational motion in X, Y or Z. They are often paired with accelerometers for inertial guidance systems, 3D motion capture and inverted pendulum type applications.
Magnetometers can sense where the strongest magnetic force is coming from, generally used to detect magnetic north, but can also be used for measuring magnetic fields. When combined with accelerometers and gyroscopes you can stabilize orientation calculations and also determine orientation with respect to the Earth.
Many 6-DoF sensors, which combine accelerometer and gyroscope or compass, accelerometer and magnetometer, and 9-DoF sensors that have 9DoF IMU accelerometers and gyroscopes and magnetometers.
