USB TO TTL FT232RL با کانکتور MINI USB:
With the development of computer technology , parallel and serial ports on the PC slowly disappeared , and now even the parallel port of the desktop are rare . But for engineers, parallel and serial interfaces are essential , especially in the serial . For computers without serial ports , the most convenient solution is to use USB to serial chip to virtual serial port out , many manufacturers have produced such a chip , such as silicon LABS of CP210x series , TI ‘s TUSB3410, Nanjing Qin Heng CH34x series, FTDI’s FT232 series , Prolific ‘s PL230x series, Echo ‘s ARK3116 so on. From the stability point of view, the most reliable or FT232 series , you can use it to ease the debugging process without fear of a blue screen appears.
FT232R chip is a single-chip solution , generally do not need to use basic peripherals , and even crystal , USB matching resistor , place the product information have been integrated in the internal EEPROM of the . FT232R There are some more useful features, details can be found FT232R data sheet .
Using FTDI FT232RL chip companies ;
FT232RL chip lead all the signal port , TTL / CMOS level ;
RXD / TXD Transceiver Communications LED ;
USB -powered, 5V or 3.3V selectable interface level ( if you need other levels can be directly provided on the VCC and GND pin target voltage)
