This is a basic breakout board for
the FTDI FT232RL USB to serial IC. 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 applications. 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 allows an Arduino target to auto-reset when a new Sketch is downloaded.
This is a really nice feature to have and allows a sketch to be downloaded
without having to hit the reset button. This board will auto reset any Arduino
board that has the reset pin brought out to a 6-pin connector.
labeled BLK and GRN correspond to the colored wires on the FTDI cable. The black
wire on the FTDI cable is GND, green is CTS. Use these BLK and GRN pins to align
the FTDI basic board with your Arduino target.
This board has TX and RX
LEDs that make it a bit better to use over the FTDI cable. You can actually see
serial traffic on the LEDs to verify if the board is working.
was designed to decrease the cost of Arduino development and increase ease of
use (the auto-reset feature rocks!). Our Arduino Pro boards and LilyPads use
this type of connector.One of the nice features of this board is
a jumper on the back of the board that allows the board to be configured to
either 3.3V or 5V (both power output and IO level). This board ship default to
5V, but you can cut the default trace and add a solder jumper if you need to
switch to 3.3V
