What is CCU? It is the most important port in the KUKA robot control system and is also the most prone to failure. It can be said that all electrical components’ distribution devices and communication interfaces, as well as all communication data, must pass through here for transmission to the control system. Below is a … Read more
This article mainly introduces the usage of the arbitrary waveform output board based on RTUBOX-206. The arbitrary waveform output board converts simulation data from CSV files into analog signals and outputs them to the oscilloscope terminal. The main operation steps consist of 2 steps: (1) Generate arbitrary waveform simulation files (*.csv files) through MATLAB simulation; … Read more
When buying a computer, you also need to consider its value retention. Customers, your budget is definitely not that generous, so the components you choose may inherently retain value better. The actual performance iteration speed of computer components is getting faster, and the value retention capability of the main components is correspondingly worse. The main … Read more
DIY manufacturers, also known as “board manufacturers”, are primarily known in the desktop DIY community, with brands like Asus, MSI, and Gigabyte being prominent. They not only release new notebooks every year but also dominate sales in desktop motherboards and graphics cards. Recently, another board manufacturer has entered the notebook industry, which is – Colorful. … Read more
