What is Arduino®
Arduino
®
is an open-source prototyping platform based on easy-to-use hardware and
software. Arduino
®
boards are able to read inputs
–
light-on sensor, a finger on a button or a
Twitter message
–
and turn it into an output
–
activating of a motor, turning on an LED,
publishing something online. You can tell your board what to do by sending a set of
instructions to the microcontroller on the board. To do so, you use the Arduino
programming language (based on Wiring) and the Arduino
®
software IDE (based on
Processing). Additional shields/modules/components are required for reading a twitter
message or publishing online. Surf to

Product Overview
The WPI440 is a USB-to-serial UART/TTL interface based on the FT232RL chip. It offers an
easy way to add USB capability to microcontrollers, e.g. Arduino
®
or WPB439.
Use this to give your own breadboard Arduino
®
USB capability for bootloading or
downloading sketches.
FTDI FT232RL USB to TTL serial converter adapter module 5 V and 3.3 V for Arduino
®
(5-
3.3 V can be selected by a switch on the board).
RXD/TXD and power LEDs are provided on the WPI440.
The board is over-current protected by a 500 mA self-restoring fuse.
The WPI440 includes a DTR pin needed to auto-reset Arduino
®
when downloading to your
device.
