CP2102 module USB TO TTL USB to serial port module UART STC downloader


Little common sense (very important):

TXD: Transmitting terminal, generally expressed as its own transmitting terminal, normal communication must be connected to the RXD of another device.

RXD: Receiving end, generally expressed as its own receiving end, normal communication must be connected to the TXD of another device.

The TXD of itself is always connected to the RXD of the device during normal communication!

Self-receiving and self-transmitting: RXD is connected to the TXD of other devices during normal communication, so if you want to receive the data sent by yourself, as the name suggests, that is, you receive the data sent by yourself, that is, your own TXD is directly connected to RXD to test its own transmission and reception Whether it is normal or not is a quick and simple test method. When a problem occurs, the first test is performed to determine whether the product is faulty. Also called loopback test.


Level logic:

TTL level: Usually data is expressed in binary, and it is stipulated that +5V is equivalent to logic "1", and 0V is equivalent to logic "0", which is called TTL signal system, which is positive logic

RS232 level: use -12V to -3V, which is equivalent to logic "0", +3V to +12V logic level, which is equivalent to logic "1", which is negative logic


product manual:

1. The main chip is CP2102, and a virtual serial port is generated after installing the driver

2. USB power supply, 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 always be on after the driver is installed correctly, the transceiver indicator will flash during communication, the higher the baud rate, the lower the brightness

4. Support baud rate from 300bps to 1Mbps

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 check

6. Support operating system: windows vista/xp/server 2003/200, Mac OS-X/OS-9, Linux

7. The USB head is male, which can be directly connected to the computer USB port

8. SMD components are produced by SMT process with stable quality

9. The volume without USB head is: (mm)
