Learn in the novice boot camp to start a brushless motor to rotate.
The hardware design main control chip uses Hi3861, which is a highly integrated 2.4GHz SoC WiFi chip that supports OpenHarmony and provides an open and easy-to-use development and debugging operating environment. The LM1085T-5.0 chip is used to convert the external power supply into 5v voltage to power the servo; the SSP1117-3.3V is used to convert the 5V voltage into 3.3 to power the chip. Use Lichuang EDA standard board to complete the schematic and PCB design. In this part, I encountered the following problems: 1. I forgot to add the power switch when designing the schematic diagram. Although it does not affect the operation of the chip, the problem is that as soon as the battery is installed, the chip starts to work, which is not conducive to subsequent development. , so we can only connect a switch to the battery box by welding a hole plate; 2. In the power supply part, there is no protection circuit. When using it, I accidentally connected the positive and negative poles of the battery reversely, burning out the two power chips. When soldering, the pins of the PCA9685 chip are relatively dense and difficult to solder, so you should be careful. Use Solidwork to complete the design of the mechanical structure. When installing soilwork again, the error as shown in the picture is prompted; the final solution is to change the 2020 version of the installation package,

My first EDA design - induction voltage pen EDA
Introduction: EDA learning results—inductive voltage pen
This induction voltage pen is a small device designed and produced based on the principle of signal amplification by triodes that can detect whether there is voltage near the socket. It is not only simple in function, easy to use, but also compact and beautiful.
This is the first result after initial learning of EDA. I hope you all like it!
By the way, please wish me a smooth final exam on the 20th and good grades! ✍✍

Polytechnic University_PCB Commemorative Card
Introduction: PCB card of Xi'an University of Science and Technology College of Science and Technology
The PCB commemorative card of Xi'an University of Technology College of Science and Technology
shows the college's motto and design plan on the front, and functional modules and three USB2.0 expansion interfaces on the back. One driver-free option is 150Mps speed WIFI or 10m/s speed 32G storage U disk. Due to the flatness of the card surface and process limitations, only double-layer boards can be drawn. The WIFI uses module 7601B module and vinyl USB flash drive. The next batch of four-layer boards will be produced in small batches, using VL812 to control USB3.0 high-speed HUB, and IS903 to control 64G high-speed USB3.0 U disk.
There are painted basketball, football, badminton, and tennis courts, which you can pick up on demand. The project needs to be opened in an editor to see it. When I look at the project here, it seems to be blank, but in fact it is all drawn. Only one welding option can be selected between the WIFI module and the USB flash drive. The selection pad is reserved and the default is the WIFI module. If you do not solder the U disk, do not short-circuit the pad. Signal reflection will seriously affect the stability and cause unrecognition. If both are soldered together, it will not be recognized. You can change this yourself and just pull the USB over.
