One module has six functions. This 6-in-1 multifunctional serial converter supports USB-TTL, USB-232, USB-485, TTL-232, TTL-485, and 232-485 converting functions and is 3.3V/5V compatible. It works well with mainstream operating systems such as Windows and Linux. There is a 500mA fuse protection circuit integrated on the module for protecting the device against damage caused by short-circuit or over-current. The on-board indicator light indicates the working status of the device: USB is selected for the COM port (Yellow light) On, data receiving RX (Red light) Flashes, data transmitting TX (Green light) Flashes.
