#Usb 2.0 serial driver arduino install#
The RS232 level:-12V to-3V, which is equivalent to logic "0", +3 V to +12 V, the logic level is equivalent to logic "1" is negative logic,ġ, the main chip CP2102, install the driver generates virtual serial portĢ, USB to take power, and interface 3.3V (<40mA) 5V, GND, TX, RX, the signal pin level is 3.3V, positive logicīoard status indicators, transceiver LED status indicator lit, install the correct drivers, transceiver indicator flashes when communication baud rate the higher the lower the brightnessĤ, support the baud rate from 300bps to 1MbpsĬommunication format support: 1) 5, 6, 7, 8 data bits 2) support for 1, 1.5, 2 stop bits 3) odd, even, mark, space, none parityĦ, support for the operating system: Windows Vista / xp / Server 2003/200 Mac OS-X/OS-9, Linux TTL level: usually binary, requiring +5 V equivalent to the logic "1", 0 V is equivalent to a logic "0", referred to as TTL signal system is the positive logic
