USB-UART USB-COM USB-TTL RS232  Convert конвертер адаптер на CP2102 Red 5V 3, 3V для Arduino ГБО и т. д.   CP2102 Red:   Tips ( very important ) : TXD: the sender , usually expressed as its sender , the normal communication must be connected to another device RXD. RXD: the receive side, generally expressed as the receiving end of their normal communication to another device connected to TXD. When normal communication TXD never received their equipment RXD! Collected spontaneously : normal communication other devices connected RXD TXD, so if you want to receive data sent their name suggests, it is their own transmitted data received , which is connected directly to its own TXD RXD, used to send and receive the test itself is normal, is the quickest and easiest way to test if a problem occurs first do the test to determine whether a product failure. Also known as the loopback test . Level
