The main chip is CP2102, and a virtual serial port is generated after the driver is installed2. USB power supply, the leading interface includes 3.3V (\u0026lt;40mA), 5V, GND, TX, RX, signal pin level is 3.3V, positive logic3. On-board status indicator and transceiver indicator, the status indicator will be on when the driver is installed correctly, and the transceiver indicator will flash during communication.4. Support baud rate from 300bps to 1Mbps5. Communication format support: 1) 5, 6, 7, 8 data bits; 2) support 1, 1.5, 2 stop bits; 3) odd, even, mark, space, none check6. Supported operating systems: windows vista \/ xp \/ server 2003\/200, MAC0S-X \/ OS-9, Linux7. The USB head is a male head, which can be directly connected to the USB port of the computer8.
