FT232RL FTDI USB To TTL Serial Converter and MAX232 IC. MAX232 is used for TTL/CMOS to RS232 conversion. Meaning most of our Microcontrollers (PIC/ARM/Atmel) operates on TTL/CMOS logic that is it communicates through either 0V or +5V, but our computers work with the help of RS232 which operates at logic level -24V or +24V. So, if we have to interface these microcontrollers with Computer we need to convert the TTL/CMOS logic to RS232 logic. Hence if you are looking for an IC to perform this conversion and interface a Microcontroller with your computer then MAX232 IC is the right one for you. FT232RL FTDI USB To TTL Serial Converter Adapter Module. RXD / TXD transceiver communication indicator, USB power supply, can choose 5V or 3.3V, set by jumper With over current protection, using 500mA self-restore fuse, Pin definition: DTR, RXD, TX, VCC, CTS, GND.
