Keyestudio FTDI Basic program downloader + Cable / USB switch TTL FT232/FCC Certification for Arduino
With the development of computer technology, parallel and serial ports on your PC slowly disappeared, and now even the parallel port of the desktop are rare. But for engineers, parallel and serial interfaces are essential, especially serial port. For no serial computer, the most convenient solution is to use a USB to serial chip to a virtual serial port out, many manufacturers have produced such a chip, such as silicon LABS of CP210x series, TI's TUSB3410, Nanjing Heng Qin CH34x series, FTDI's FT232 series, Prolific's PL230x series, Echo's ARK3116 so. From the stability point of view, is still the most reliable FT232 series, you can use the debugger it to ease the situation without worrying about the blue screen appears.
FT232R chip is a single-chip solution, generally does not require the use of basic peripherals, and even crystal, USB matching resistor placed EEPROM product information have been integrated within it. FT232R some of the more useful features, details can be found in FT232R data sheet.
· Using FTDI's FT232RL chip;
· FT232RL chip lead all the signal port, TTL / CMOS level;
· RXD / TXD transceiver communication indicator;
· USB powered, optional 5V or 3.3V Interface level (if other levels, target voltage can be provided directly on the VCC and GND pins).
