CP2102 USB TO TTL USB TO serial port module UART STC downloader
Point (pretty important) :
TXD: sending close, generally represented as its possess sending close, typical communication must be connected to the RXD of yet another unit.
RXD: the getting conclude, which is normally represented as its possess obtaining end. In normal communication, it will have to connect to the TXD of another device.
Usual conversation when the TXD alone is often connected to the system RXD!
Self profits: Typical communication TXD RXD join other gadgets, so if you want to get their data, as the title implies, is receiving themselves to send out information, is immediately linked to the RXD TXD itself, that is, alone, applied to test regardless of whether the sending and getting of normal is quickly and easy exam process, when a issue to start with do this test to establish irrespective of whether the products failure. Also called loopback examination.
Amount logic:
TTL level: Information illustration is commonly binary. It is stipulated that +5V is equivalent to rational “1” and 0V is equivalent to rational “”. This is identified as TTL sign method and is favourable logic
RS232 amount: -12v to -3V, equal to logic “”, +3V to +12V logic amount, equivalent to logic “1”, is negative logic
Products description:
1. The primary chip is CP2102, and the digital serial port is created after the driver is set up
2, USB energy, the outlet port includes 3.3V (<40mA), 5V, GND, TX, RX, signal pin level is 3.3V, positive logic
3, onboard state indicator, transceiver indicator, the correct installation of the driver after the state indicator light will be steady on, transceiver indicator in communication will blink, the higher the baud rate, the lower the brightness
4, support from 300bps to 1Mbps baud rate
5, communication format support: 1) 5,6,7,8 data bits 2) support 1,1.5,2 stop bits 3) odd,even,mark,space,none
6. Supported operating system: Windows Vista/XP/Server 2003/200,Mac OS-X/OS-9,Linux
7, USB head for the male head, can be directly connected to the COMPUTER USB port
8. SMT components are produced by SMT process with stable quality
9, without USB head volume :(mm)
