The filter is one of the essential key components in the RF system. It is mainly used for frequency selection - allowing the required frequency signal to pass through and reflecting the unwanted inter...
Abstract: This paper briefly describes the principle of the forward circuit commonly used in the design of DC/DC power modules, and proposes an improved circuit with higher efficiency, smaller size, s...
GPIO operations can be performed through the sys file system interface. When the file system operates GPIO, you must first check whether the GPIO you want to operate is occupied by other drivers. If i...
There have been posts before that reflect that when performing UART testing, since the UART interface on the board does not provide power to the development board, two USB cables are required, one for...
