10-in-1 USB Serial Adapter, CH340 CP2102 USB to TTL RS485 RS232 Converter Module
- 10-in-1 USB-to-Serial Adapter: This multifunction USB-to-serial adapter converts a computer USB port into serial communication interfaces, supporting USB-to-TTL, USB-to-RS232, and USB-to-RS485 applications for development, debugging, maintenance, and industrial communication.; CH340G Serial Conversion Chip: Built with a CH340G USB-to-serial solution, the adapter provides a practical communication channel for computers without native serial ports and helps traditional serial devices connect through USB as convenient plug-and-play devices.; One-Button Communication Mode Switching: The module supports one-button communication channel setup. Press the button once to switch the communication mode, making it easier to change between different serial interface configurations during testing or field debugging.; LED Status and Data Indicators: Green and red LEDs indicate communication and working status. Four green channel LEDs show the currently active channel, while the data indicator flashes when data is being transmitted, helping users quickly identify connection and communication activity.; Wide Compatibility & Power-Off Memory: Supports Windows 98 / ME / 2000 / XP / Win7 / Win8 / Win10 systems in 32-bit and 64-bit versions. The adapter also supports dual-channel serial voltage testing from 0 to +30V and retains system parameters after power loss, restoring the previous communication state after restart.
