GPS Receiver – GP-20U7 (56 Channel)
The GP-20U7 is a compact GPS receiver with a built-in high performances all-in-one GPS chipset. The GP-20U7 accurately provides position, velocity, and time readings as well possessing high sensitivity and tracking capabilities. Thanks to the low power consumption this receiver requires, the GP-20U7 is ideal for portable applications such as tablet PCs, smart phones, and other devices requiring positioning capability.
This 56-channel GPS module, that supports a standard NMEA-0183 and uBlox 7 protocol, has low power consumption of 40mA@3.3V (Max), an antenna on board, and -162dBm tracking sensitivity. With 56 channels in search mode and 22 channels “All-In-View” tracking, the GP-20U7 is quite the work horse for its size.

SparkFun OpenLog
The SparkFun OpenLog is an open source data logger that works over a simple serial connection and supports microSD cards up to 32GB. The OpenLog can store or “Log” huge amounts of serial data and act as a black box of sorts to store all the serial data that your project generates, for scientific or debugging purposes.
The SparkFun OpenLog uses an ATmega328 running at 16MHz thanks to the onboard resonator. The OpenLog draws approximately 2-3mA in idle mode. During a full record OpenLog can draw 10 to 20mA depending on the microSD card being used.
All data logged by the OpenLog is stored on the microSD card. Any 512MB to 32GB microSD card should work. OpenLog supports both FAT16 and FAT32 SD formats.

SparkFun Micro OLED Breakout
The SparkFun Qwiic Micro OLED Breakout is a Qwiic-enabled version of our popular Micro OLED display. The small monochrome, blue-on-black OLED screen presents incredibly clear images for your viewing pleasure. It’s the OLED display is crisp, and you can fit a deceivingly large amount of graphics on there. This breakout is perfect for adding graphics to your next project and displaying diagnostic information without resorting to a serial output, all with the ease of use of our own Qwiic Connect System.
This version of the Micro OLED Breakout is exactly the size of its non-Qwiic sibling, featuring a screen that is 64 pixels wide and 48 pixels tall and measuring 0.66″ across. But it has also been equipped with two Qwiic connectors, making it ideal for I2C operations. We’ve also added two mounting holes and a convenient Qwiic cable holder incorporated into a detachable tab on the board that can be easily removed thanks to a v-scored edge.

Programming and Coding
Most of the development in the world is all because of technology. Technology has grown much faster than everything else. All the technology is developed because of coding and programming. Programming and coding hold a vital role in development. It also includes developments from small projects to big projects.
The programming vs coding difference lies in the very definition of both processes. Programming is the general process of creating a program that follows certain standards and performs a certain task. Coding, on the other hand, is a part of programming that deals strictly with converting the language we understand into binary commands for the machine.
As we have discussed before in our discussion on programming vs coding, coding is just a part of programming. Yet, it still requires some time and skill to learn. Programming languages are very different from natural languages, and their syntax can sometimes be very confusing. The hardest languages are low-level ones that are close to actual processor instructions.
Programming
Programmers, on the other hand, need to review documentation and perform analysis besides coding which requires extra tools. You can find various code analysis tools, code generators, databases and testing frameworks in their inventory. Programming is passing the instructions and information to the computer that describes how a program should be carried out. Programming helps computers to perform certain actions. Various types of programming languages available in the market, like C, C++, Java, Python, etc., help develop new and creative technology.
Coding
Since coding is a simple act of translation, you don’t need much to perform it. In most cases, a simple text editor would suffice. Coding is a process of establishing a successful communication between a software program and the computer hardware. The compilers translate the program into assembly language. The coding process converts the assembly language to Binary Coded Signals.
Computer systems are electronic devices that rely on binary coded signals for communication and functioning. The two types of binary coded signals are o’s and 1’s. These signals are generated using switches and transistors. In the process of coding the high-level language and the assembly level languages are translated into binary codes and the communication between the computer hardware and software application is established.
Microcontrollers – Arduino IDE
Since the launch of the Arduino open-source platform, the brand has established themselves at the center of an expansive open-source community. The Arduino ecosystem is comprised of a diverse combination of hardware and software. The versatility of Arduino and its simple interface makes it a leading choice for a wide range of users around the world from hobbyists, designers, and artists to product prototypes.
Arduino code is written in C++ with an addition of special methods and functions, which we’ll mention later on. C++ is a human-readable programming language. When you create a “Sketch”, the name given to Arduino code files. The Arduino Integrated Development Environment (IDE) is the main text editing program used for Arduino programming. It is where you’ll be typing up your code before uploading it to the board you want to program. Arduino coding it is processed and compiled to machine language.

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.

DS3231 Precision RTC FeatherWing
A Feather board without ambition is a Feather board without FeatherWings. This is the DS3231 Precision RTC FeatherWing it adds an extremely accurate I2C-integrated Real Time Clock (RTC) with a Temperature Compensated Crystal Oscillator (TCXO). 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 time keeping, even when main power is lost. Great for datalogging and clocks or anything where you need to really know the time.
