Description

CP2102 module USB TO TTL USB to serial port module UART STC downloader
Little common sense (very important):
TXD: The sender is generally represented as its own sender. Normal communication must be connected to the RXD of another device.
RXD: The receiving end is generally represented as its own receiving end, and normal communication must be connected to the TXD of another device.
In normal communication, the TXD of its own is always connected to the RXD of the device!
Self-receiving: RXD is connected to the TXD of other devices during normal communication. Therefore, if you want to receive the data sent by yourself as the name implies, that is, you receive the data sent by yourself, that is, its own TXD is directly connected to RXD, which is used to test its own transmission and reception. Whether it is normal or not is the fastest and easiest test method. When a problem occurs, the test is first performed to determine whether the product is faulty. Also known as loopback testing.
Level logic:
TTL level: Usually the data indicates binary. The specified +5V is equivalent to logic "1". 0V is equivalent to logic "0". It is called TTL signal system and is positive logic.
RS232 level: -12V to -3V, equivalent to logic "0", +3V to +12V logic level, equivalent to logic "1", is negative logic
product manual:
1. The main chip is CP2102. After installing the driver, a virtual serial port is generated.
2, USB power, the output interface includes 3.3V (<40mA), 5V, GND, TX, RX, the signal pin level is 3.3V, positive logic
3, on-board status indicator, transceiver indicator, the status indicator will be on after the driver is properly installed, the transceiver indicator will flash when communicating, the higher the baud rate, the lower the brightness
4, support baud rate from 300bps ~ 1Mbps
5, communication format support: 1) 5,6,7,8-bit data bits; 2) support 1,1.5,2 stop bits; 3)odd,even,mark,space,none check
6, support operating system: windows vista / xp / server 2003 / 200, Mac OS-X / OS-9, Linux
7, USB head is male, can be directly connected to the computer USB port
8, the chip components are produced by SMT process, the quality is stable
