Contains the design principles of four-wing aircraft
500W fully digital AC-DC power supply (D-SMPS) based on STM32F334C8 microcontroller
15 V/200 mA step-down converter based on VIPER122
The system consists of STC89C52 microcontroller, 4*4 matrix keyboard, buzzer, reset circuit and crystal oscillator circuit, relay, etc. The 4*4 keyboard is mainly used for password input and modification, buzzer alarm, reset circuit and crystal oscillator circuit with STC89C52 The single-chip microcomputer constitutes the smallest system of single-chip microcomputer. It has functions such as setting and modifying 6-digit user passwords, alarming for incorrect input, and alarming for incorrect passwords. This system is low in cost and practical in function.
LPC-Link 2 is an extensible, stand-alone hardware debugger that can be configured to support a variety of development tools and IDEs using a variety of downloadable firmware. Additionally, it serves as an evaluation board in its own right for evaluating NXPLPC4370 triple-core MCU. Combined with the Embedded Artists add-on board, it can be used as an oscilloscope or logic analyzer!
With TMS320F28033 as the core, it is composed of signal amplification circuit, signal acquisition circuit, data storage and processing module, system control and display module and other parts.

When a substance burns, it produces smoke and heat, and also produces visible or invisible light radiation that is not found in the atmosphere. Flame detector, also known as photosensitive fire detector, is a fire detector used to respond to the light characteristics of fire, that is, to detect the light intensity of flame burning and the flicker frequency of flame. Infrared flame detector is a flame detector that is sensitive to the longer wavelength infrared light radiation in the flame. According to the different detection bands, it is divided into single band, dual band and three band.
