Description: 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.
The pins labeled BLK and GRN correspond to the colored wires on the FTDI
cable. The black wire on the FTDI cable is GND, green is DTR. Use these BLK
and GRN pins to align the FTDI basic board with your Arduino target.
There are pros and cons to the FTDI Cable vs the FTDI Basic. This board has TX
and RX LEDs that allow you to actually see serial traffic on the LEDs to verify
if the board is working, but this board requires a miniB cable. The FTDI Cable
is well protected against the elements, but is large and cannot be embedded into
a project as easily. The FTDI Basic uses DTR to cause a hardware reset where the
FTDI cable uses the RTS signal.
This board 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.
