RX = Serial data Receive pin, connects to TX on the device.DTR = Data Terminal Ready – an output used for flow control if needed (usually not used).The pin-out of the right angle header is as follows. You will also need to connect the GND pin to ground on the device. There are transmit and receive LEDs on the module that shows activity on these lines. RX on module goes to TX on device and TX on module goes to RX on device. On the TTL side, most applications will just use the RX and TX pins cross-connected between the FT232RL module and your device that you are trying to control. The USB end plugs into your computer USB port using a standard USB to mini-B USB cable. The breakout points also allow straight headers to be soldered in so that the module can be mounted flat on a breadboard if desired. These normally aren’t needed, but do provide easy access points to support atypical applications.
In addition to the header, the I/O from those pins along with additional I/O from the pins of the FT232RL chip are brought out to breakout points along the edge of the board. The Serial TTL interface is brought out to a right angle header. The module uses a Mini-B style USB connector for connection to the PC. If operating at 3.3V, this power comes from a regulator built into the FT232RL chip and the output is limited to only 50mA.

When operating at 5V, the full USB maximum current of around 500 mA is available. The board has a jumper that allows you to select between supplying 5V or 3.3V to this VCC pin. That USB power is also made available on the header VCC pin for use in powering up the board that the module is plugged into if needed. Power for this module come from the USB port. This is commonly required when you are programming a new board through its programming interface if it does not have a USB port. This adapter is based on the FT232RL chip and provides a bridge for communicating between a typical TTL level serial communication (UART) port as found on many uCs and the USB port normally found on a computer.
