This week, I ushered in the 2019 National International Competition. As the booth, the circuit related to the power game has become popular, and most of the popular circuits are related to the power games, I wish to participate in the competition. Classmates can achieve ideal achievements! Let's take a look at this TOP circuit.
TOP10: 2019 Electronic Design Competition Equipped Power Module
The road output power, the electric game has been used in several years, one of the people, the output is 12 V, the positive and negative 5V. 88mm * 88mm, the small partner with time can be proofed, the board puts the LOGO of the school. Beautiful, very practical!

TOP8: Automatic Watering System and Water Level Indicator Complete Project (Schematic + Source Code + Video Demo)
In this project, we talk about an automation system including the entire watering system. The automatic watering system is such a system that measures soil humidity by soil humidity sensor, and plants began to water. We don't need to control water, because the device will automatically water in need.

TOP7: Hardware debugging tool with HUB_JLINK_CH340 function (schematic + source code + jlink firmware)
HUB_JLINK_CH340 function
The GL850 is a 4-port standard USB HUB controller that follows USB 2.0 standards. 2 USB ports reserved,
The CH340 is a transfer chip of a USB bus that implements a USB turn serial port.
Collect JLink OB function, easy to download, debug the ARM program.
Normally, it is necessary to ensure that the USB-MINI line is small, otherwise easy chips are not low.

TOP3: 2015 National International Chalsey Design, First Award Works!
This wind swing control system mainly includes a single-chip control module, a power module, a posture acquisition module, a wind swing module, a liquid crystal display module, a host computer, and a wind spring mechanical structure. The wind is all over the upper end of a tube of about 60 cm to 70 cm, and a set of (2 to 4) axial flow hangs is hang down. The posture acquisition module on the pendulum is collected from the current posture angle and feeds back to the microcontroller. The single chip microcomputer handles the feedback back data by a series of algorithms and PID control, and then controlling the fan speed of different positions by controlling the PWM duty cycle to achieve control of wind swings.
