USB-serial port conversion circuit made with CP2102 chip

CP2102 is a USB-to-serial chip developed by SI1bab. It is small in size and can form a simplest USB-UART solution without any peripheral components. The communication rate can reach 1Mbps, which makes it easy to upgrade serial products to USB ports. The simplest application schematic of CP210 can be simplified to form a high-performance USB-UART converter without any peripheral components. The schematic diagram is as follows

Of course, if there is enough space, it is recommended to add some peripheral components, such as decoupling capacitors, power indicators, etc., as shown in the figure below
