The most successful drone DIY project in history is actually... (with hardware block diagram + schematic diagram + fly
With the continuous advancement of drone technology, the capabilities of drone equipment have expanded significantly, and the cost to purchase drones has become more affordable. In the past, drones were expensive, often costing thousands or even tens of thousands of dollars, which discouraged most civilians from buying them. However, as the drone market has rapidly developed, the number of drones has increased. Now, for just a few hundred dollars, you can purchase an entry-level drone that is both low-cost and feature-rich.
That said, there are still some "chicken ribs" in the primary drones available on the market. Some may have poor quality, incomplete features, short battery life, or a less-than-smooth remote control experience.
So, have you ever considered building your own unique drone?
Xiaobian has some great news to share! On the 8th of this month, Zhang Fei, a veteran in hardware design with over ten years of experience, collaborated with the Electronic Enthusiasts College to launch a crowdfunding campaign for the Zhang Fei quadcopter on the enthusiast crowdfunding website!
Now, you can also assemble a quadcopter drone yourself. From the inside out, you can choose the functions you need, the interfaces to achieve, communication, video, aerial photography, GPS—whatever you want, a complete "machine" is at your fingertips!
Before we dive into the topic, let's take a look at how the configuration of the drone DIY main control board is!
Main control chip: STM32F373 CCT6
Attitude detection: MPU6500
Wireless communication: NRF51822
Human-computer interaction: red, green, blue monochrome LED

In addition, you can also choose to use various expansion modules to achieve more functions of the drone (coordinate positioning, short video shooting, fixed-point hover, etc.). Note that the following accessories are not included in this drone crowdfunding event! You can add the features you want to implement according to your needs.
For example:
Barometer
To realize the precise coordinate positioning and height measurement of the drone, and realize the function such as fixed-point hover, automatic navigation.
Electronic compass
UAV flight angle and direction positioning control.
GPS
Needless to say, this is what everyone on earth knows!
Ultrasonic
Realize ultrasonic detection, automatically avoid obstacles, and measure the distance between the drone and the obstacle of the object.
Wait, etc....
In the process of making drones, you can also use our drones to make videos, from shallow to deep, step by step to understand the drone structure from the rack, blades, motors, batteries, remote control systems, flight control systems, how does the remote control realize the vertical, pitch, roll, and yaw motion principles, how to achieve precise positioning hover, intelligent out of control protection, automatic return, low voltage alarm, heading lock, etc... Whether you are a novice or a veteran, all churches You do a whole set of drone methods! So, if you want to systematically learn the drone production process, remember to buy the full version of the video!

Detailed explanation of the circuit design of the flight control expansion interface module
Detailed explanation of sensor module circuit design
Detailed explanation of the circuit design of 2.4G transmitter and receiver module
Detailed explanation of the peripheral circuit design of the flight control main chip STM32F373CCT6
Very detailed hardware circuit design outline, not afraid that you will not learn!
Flight control software flow chart
The STM32 software design part explains everything from environment framework construction, pin and serial port configuration debugging, to ADC signal acquisition, sensor, and four-axis algorithm implementation.
In addition, the enthusiast college also set up a special group of Zhang Fei crowdfunding qq group to help you answer all the difficult problems encountered in the DIY drone process, difficult points. As long as you want to get, what questions do you ask, we let the professional technicians help you answer!
Zhang Fei four-rotor drone crowdfunding activities part of the problem
1. I heard that Zhang Fei’s lectures have major innovation changes.
In this crowdfunding activity, Teacher Zhang Fei did have great innovations in software lectures. The video provided by this event will be explained by hardware, so the learning efficiency will be greatly improved!
2, just contact with drones, electronic novices, students zero foundation, can you learn?
The crowdfunding campaign provides a video version of the package, and the knowledge points explained in the video are very detailed. From motor control, principle design related calculations, PCB Layout, sensors, Bluetooth RF antennas, product debugging, etc. In addition, you can also combine your own experience, innovate, and rewrite the code to achieve the function you want!
3. How many packages are there for the quadrotor aircraft crowdfunding activities?
There are 5 packages for this crowdfunding activity, which are 1 yuan package (one lucky person for every 100 people), 318 yuan package (no video version), 418 yuan package (including PCB Layout video part), 458 yuan package. (APP version, providing complete drone production video), 498 yuan package (providing remote control, complete drone production video)
USB 2.0 Hub
Another version of USB HUB.When comparing 2.0 and 3.0 there are a few major differences. First the transfer rates: USB 2.0 offers transfer rates of 480 Mbps and USB 3.0 offers transfer rates of 4.8 Gbps - that's 10 times faster. Note that the transfer speeds also depend on the device in use in addition to the bus type and USB ports and cables.
