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 significantly expanded, and the cost of purchasing drones has dropped dramatically. In the past, drones were expensive, often costing thousands or even tens of thousands of dollars, which discouraged most civilians. However, as the drone market has grown rapidly, the number of drones in use has increased. Now, you can purchase an affordable, feature-rich entry-level drone for just a few hundred dollars.
That said, not all entry-level drones on the market are perfect. Some may suffer from 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 is excited to share some great news! On the 8th of this month, Zhang Fei, a veteran in the hardware design industry with over ten years of experience, has partnered with the Electronic Enthusiasts College to launch a crowdfunding campaign for a four-rotor drone on a dedicated crowdfunding platform!
Now, you can build your own quadcopter drone. From the inside out, you can customize what functions you need, what interfaces to implement, whether it's communication, video, aerial photography, GPS, or anything else—everything is possible!
Before diving into the details, let’s take a look at the configuration of the DIY drone main control board:
- Main control chip: STM32F373 CCT6
- Attitude detection: MPU6500
- Wireless communication: NRF51822
- Human-computer interaction: Red, green, blue monochrome LED
- Control method: Remote control, mobile app (supports body feel)
- Charging method: One for two 1A charger
- Motor parameters: Professional custom 3.7V, 50000 rpm, 816 hollow cup motor
- Blade parameters: 50mm positive and reverse efficient three-blade paddle
- Paddle protection parameters: Patented design independent and easy-to-replace blade protection ring + rubber shock absorber landing gear
- Battery parameters: 550mAh, 3.7V, 20C
- Maximum battery life: 6 minutes
- Simulation debugging: ST-Link32 emulator
- Firmware upgrade: SWD, USB

Additionally, you can choose various expansion modules to enhance the functionality of your drone, such as coordinate positioning, short video shooting, and fixed-point hovering. Note that these accessories are not included in the crowdfunding event; you can add the features you want based on your needs.
For example:
- Barometer: For precise coordinate positioning and height measurement, enabling functions like fixed-point hover and automatic navigation.
- Electronic Compass: For UAV flight angle and direction positioning control.
- GPS: For global positioning.
- Ultrasonic: For obstacle detection and distance measurement.
And much more.
During the drone-making process, you can also use our drones to make videos, starting from the basics and gradually understanding the structure of the drone, from the frame, blades, motors, batteries, remote control systems, and flight control systems. You'll learn how remote control achieves 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, and more. Whether you're a beginner or an expert, you'll gain a comprehensive understanding of drone production. If you want to systematically learn about the drone manufacturing process, remember to purchase the full version of the video!

In addition, the enthusiast college has set up a special group for Zhang Fei crowdfunding on QQ to help you answer all the difficult problems encountered during the DIY drone process. 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).
A USB hub is a device that expands a single Universal Serial Bus (USB) port into several so that there are more ports available to connect devices to a host system, similar to a power strip. All devices connected through a USB hub share the bandwidth available to that hub.With a multi USB port HUB, you'd be able to connect all your USB hard drives at once and simultaneously transfer the photos to other. Some USB port hubs even come with SD card slots, so you could transfer the photos directly from your port hub. You wouldn't have to transfer them to your computer first.
