The NRF24L01 module is a 2.4GHz communication module. The output power channel selection and protocol settings can be set through the SPI interface. It can be connected to almost all microcontroller c...
I just started to enter this industry! This is a picture of a bridge arm of a MOS tube. I mainly want to know the function of each part and how to choose the parameter size! Thank you!...
I am a beginner. I have recently encountered some strange problems while doing RFID experiments. I used a 345uH coil in parallel with a 0402 4.7nF capacitor. The oscillation voltage measured by the os...
1. Basic Concepts of Clusters There is a common method that can greatly improve the security of servers, which is clusters. Cluster technology can be defined as follows: a group of independent servers...
6410's SDBOOT is a very convenient tool. It uses the SD card to load SD_EBOOT, then downloads the standard STEPLDR and EBOOT generated by WINCE6.0, and then enters the NANDFLASH boot mode to download ...
STM8S103F2 is used to sample current. The current sampling resistor is 50 milliohms, and is input to the chip's AD port after simple filtering by 1K and 104. The voltage on the sampling resistor is ab...
This article discusses how to wake up a touch-sensitive device such as a tablet without touching the device, using basic gesture recognition and novel proximity sensors. The article discusses the p...[Details]
Today, with the increasing integration of functions, mobile phones can also be used as portable media players (PMP), digital cameras, handheld computers (PDAs), and even global positioning systems ...[Details]
introduction
Throughout the history of automotive lighting, power has always played an important role. Initially, cars only needed headlights to see the road in the dark. Later, other light so...[Details]
Abstract: In order to generate a stable excitation signal, the design of a digital frequency synthesizer is implemented on FPGA using Verilog hardware language. The design includes accumulator, wav...[Details]
I. Introduction
In the field of power conversion, isolated converters (forward, flyback, and double-ended) with low output DC voltage all use MOSFET as the rectifier device. Since these devi...[Details]
In recent years, lighting has become an important area that countries around the world are targeting to promote energy conservation and environmental protection. According to statistics, about 20% ...[Details]
I've been studying dot matrix recently. It looks simple, but it takes a while to master it completely! The 8*8 dot matrix hardware circuit I'm making now is like this. The row is driven by 74HC138 + t...[Details]
This controller uses PIC16C54 single-chip microcomputer as the controller, and it is very easy to use: just connect a telephone line to the loudspeaker through the controller, and you can rem...[Details]
Abstract: The output of high-range acceleration sensor is less than 10 mV under the excitation of small signal. The noise of traditional test system may cover such small voltage signal, so that hig...[Details]
The rectified DC voltage is then converted back to AC using power electronics such as insulated gate bipolar transistors.
The output voltage is switched on and off at a high frequency, control...[Details]
