With the continuous development of drone technology , the functions of drone equipment have increased, and the threshold for purchasing drones has become lower and lower. Originally, thousands or even tens of thousands of prices have made most of our "civilians" discouraged. However, with the rapid development of the drone market, the number of drones has increased. Now, for three or four hundred dollars, you can buy low-cost, full-featured entry-level drones. However, after all, there are always some "chicken ribs" in the primary drones that can be bought on the market. Either the quality is not good, or the function is not complete enough, the battery life is too short, and the remote control operation fluency experience is too bad. So, have you ever planned to start DIY a unique drone? Xiaobian wants to give everyone a good news here! On the 8th of this month, more than ten years of hardware design industry, the great god Zhang Fei, and an in-depth cooperation with the Electronic Enthusiasts College, Zhang Fei four-rotor aircraft activity crowdfunding officially launched on the enthusiasts crowdfunding website! Now, you can also assemble a quadrotor drone yourself. Regardless of the drone from the inside out, what functions do you need, what interface to achieve, communication, video, aerial photography, GPS, whatever you want, a "machine" is exhausted! Before entering 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 Control method: remote control remote control, mobile APP (supporting body feeling) Charging method: one for two 1A charger Motor parameters: professional custom 3.7V, 50000 rpm, 816 hollow cup positive and negative 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: el Ink32 emulator Firmware upgrade: SWD, USB Drone front UAV reverse side In addition, you can also choose to use the 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. such as: Barometer To realize the precise coordinate positioning and height measurement of the drone, and realize the function For example: 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! Quadrotor UAV hardware circuit block diagram Drone circuit schematic Part of the circuit schematic video, will talk about the following: Detailed explanation of the design of the power circuit LDO Detailed explanation of the LED status indicator module Hollow cup motor control circuit detailed design explanation 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) The antenna assembly harness are passed heat and other kinds of tested.
