FT232RL FT232 USB TO Serial USB To UART TTL 5V 3.3V FTDI Module


The USB TO UART TTL 5V 3.3V FT232RL download Cable To Serial Adapter Module is a basic breakout board for the FTDI FT232RL USB to serial IC, Revision 2. The pinout of this board matches the FTDI cable to work with official Arduino and cloned 5V Arduino boards. it can also be used for general serial programs.

The major difference with this board is that it brings out the DTR pin as opposed to the RTS pin of the FTDI cable. The DTR pin permits an Arduino target to auto-reset when a brand new sketch is downloaded. this is a really high-quality feature to have and lets in a caricature to be downloaded without having to hit the reset button. This board will car reset any Arduino board that has the reset pin brought out to a 6-pin connector.

The pins categorized BLK and GRN correspond to the colored wires on the FTDI cable. The black wire at the FTDI cable is GND, green is CTS. Use these BLK and GRN pins to align the FTDI basic board together with your Arduino goal.
