This week, the previous 10 circuit scheme is released, covering the USB turn TTL module, six-axis gyro information summary, electromagnetic gun, can manually draw the intelligent trolley robot, five full Gigabit switch and other materials, everyone's attention Still more embarrassed to practical aspects and some creative solutions.

TOP 10: Open source project! Five full Gigabit switches created with RTL8367RB
Home LAN, PC is a Gigabit, but the TP-Link8 switch on the table is 100 megabytes. When the two machines are backed up, the peak is only around 11m / s when the two machines are backed up. Helpless brother has a resource of about 100g, which is really difficult to endure the turtle. Moreover, the book is PC2, 1 server, plus the temporary notebook, up to 5, and the 8-port switch of TP-Link is a waste and not exquisite. So I think I want to do a 5-port full Gigabit switch, and the province waste the resources of the computer Gigabit network card. . .

TOP 8: USB3.0 HUB 1 Drag 4 All Open Source (Schematic, PCB Source File, Firmware Upgrade Software & Firmware, etc.)
Since I need a lot of USB port, I specially made a HUB used. It is a relatively universal VIA VL812. The schematic is to use the official no change. It is still satisfactory that there is no incompatible thing. "Related Documents" simultaneously gives other users to USB3.0 HUB 1 drag 4 Layout, open with PADS9.5.

TOP 7: STM32F407 development board official schematic + firmware library + routine
The STM32F407 development board can interface the STM32F4 Discovery development board. STM32F4Discovery is a Cortex-M4 development board designed for high-performance STM32F4 series.
The development board is based on STM32F407VGT6 design. The development board also integrates the ST-LINK / V2 simulation downloader (but only external SWD interfaces), exempt from your additional purchase emulator or downloader. Added an acceleration sensor LIS302DL, digital microphone MP45DT02, speaker driver, and a Micro-AB USB interface.

TOP 6: Share your own PCB package library (Altium Designer)
Including yourself in a few years, 3D shows, STM32 series has STM32F103C8, VE, ZE, F105VC, F107VC. In order not to increase trouble, directly open the "libpkg" project after decompression, the schematic package and the PCB package directly correspond to it, if the package is modified, the direct compilation project is good. In order to prevent errors, the 3D model is drawn in the machine 13 Layers, the method of adding 3D models is to open the package, switch to the mechanical layer, put the 3D body, after painting, you can change the color and height.

TOP 5: Intelligent trail robot based on ARDUINO implementation can be manually drawn
The main idea is to control the rigor-based robots based on the network-based map, allowing the robotic trolley to transport the goods to the destination with your finger on the mobile screen.
In this project, I made a simple trolley that does not use feedback sensors. Therefore, the position error will accumulate over time.
The project can correct the position error by using a feedback sensor, thereby motivating someone to make a perfect carrier. This will be more convenient if it is combined with a routing algorithm such as a Dijkstra algorithm.

TOP 4: Switching Power Adapter Circuit + PCB Source File + BOM List, etc.
The US VICOR is currently the world's largest high-density power module manufacturer, and is also the only manufacturer that can produce power modules with zero voltage and zero current technology. The Vicor power module includes DC-DC, AC-DC power modules, isolated, non-isolated power module converters. The core technology of the Vicor's power module is a "zero current" switch, which makes the operating frequency of the converter reached 1 MHz, the efficiency is greater than 80%.
This document describes the 12V1.5A switching power adapter based on RM6203 designed. The switching power supply circuit is overcurrent, short circuit protection, has been mass produced by 50K, and stability is good.

TOP 3:14 level electromagnet circuit diagram, powerful steelmail (new version is about to update)
The electromagnetic main power supply partial circuit diagram, the control section is the same, each section MOS tube is discharged, the main is the parameter of the distance and the distance between the photoelectric switch. Push the object to be operated using electromagnetic force. Rapid moving effect of the object. This data can be 20 levels, usually the 14-level higher level speed is very difficult. Maximum 800m per second. Please do not hurt small animals with electromagnet. Children don't want to play!

TOP 2: STM32 control MPU6050 six-axis gyroscope - data summary
The step of typically using the MPU 6050 is the first to drive the I2C bus, then initialize the MPU 6050, read the data from the MPU 6050, and finally the processing of the data. This document describes the description of the MPU6050 three-dimensional angular sensor electronic gyroscope. The attachment content provides this MPU6050 module schematic, supporting STM32 code, related data manuals, and reference documents.
