FT232BL FT232 USB to TTL 5V 3.3V Download Cable To Serial Adapter Module + Cables for Arduino

With the development of computer technology, parallel and serial ports on the PC slowly disappeared, and now even the desktop parallel port are rare. But for engineers, parallel and serial interfaces are essential, especially serial port. For there is no serial computer, the most convenient solution is to use USB to serial chip to a virtual serial port out, many manufacturers have produced such a chip, such as silicon LABS series of CP210x, TI's TUSB3410, Nanjing Qin Heng CH34x series, FTDI's FT232 series, Prolific is PL230x series, Echo of ARK3116 like. From the stability point of view, the most reliable or FT232 series, you can use the debugger to it peace of mind without worrying about a blue screen appears.
