USB2SERIAL V3.0 is a FT232 based protocol converter which can be used as the following
- USB to RS485 converter
- USB to RS232 converter
- USB to Serial (5V/3.3V) converter
- FT232 Development Board with Screw terminals
- RS485 Breakout Board
- RS232 Breakout Board
Rs 1370/-
Device Driver Software
- USB2SERIAL V3.0 uses FT232 chip from FTDI at the USB end.
- The VCP drivers for FTDI FT232RL can be downloaded from here.
- Most Linux versions already have the FT232 drivers in the kernel so the device will work without installing any drivers.
