Brand Crius Model V1.0 5V Quantity 1 Color Blue Material PCB Features The newest version Specification 6-Pin 3.3 5V Application MWC MultiWii Lite / SE English Manual/Spec N/A Other A product for Arduino that works with official Arduino boards. This is the newest revision of our FTDI BASIC; It now uses a SMD 6-pin header on the bottom which makes it smaller and more compact; Functionality has remained the same; 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 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; 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; Document: Windows 32/64 drive: http://www.ftdichip.com/Drivers/VCP.htm; 2.
