FT232RL - USB to Serial TTL module - 3.3V/ 5V operation
FT232RL is among the most reliable and matured USB to serial bridge in the market. The driver is available for all the popular operating systems. This particular module has all the pins of FT232RL break out to 2.54mm pith headers. It is useful for implementing full modem (RS-232) serial functionality and can also be used to uplaod sketches on arduino boards and AVR chips with arduino boot loader. Works at 3.3V logic level hence ideal for using with 3.3V devices like ARM MCUs or ESP8266 device which operates only at 3.3V.
