FTDI Basic Breakout – 5V  FT232RL晶片 美國 SparkFun 原裝進口

這是 Sparkfun  FTDI Basic 的最新版本。我底部使用SMD 6針頭,這使得它更小更緊湊。功能一直保持不變。這是FTDI FT232RL USB串行IC的功能擴展板。該板的引腳排列與FTDI電纜匹配使用官方Arduino和副廠的5V Arduino板。它也可以用於一般串行應用。與該板的主要區別在於它引出DTR引腳,而不是FTDI電纜的RTS引腳。當下載新的草圖時,DTR引腳允許Arduino目標自動復位。這是一個非常好的功能,讓您可以下載草圖,而無需點擊重置按鈕。

標記為BLK和GRN的引腳對應於FTDI電纜上的有色導線。FTDI電纜上的黑線為GND,綠色為CTS。使用這些BLK和GRN引腳將FTDI基板與Arduino目標對齊。該電路板具有TX和RX LED,通過FTDI電纜可以更好地使用。您實際上可以看到LED上的串行流量,以驗證電路板是否正常工作。該板旨在降低Arduino開發成本,並提高易用性(自動重置功能!)。我們的Arduino Pro板和LilyPads使用這種類型的連接器。該板的一個很好的功能是板背面的跳線,允許將板配置為3.3V或5V(電源輸出和IO電平)。該闆卡默認為5V,但如果需要切換到3.3V,則可以切斷默認軌跡並添加焊接跳線。

SparkFun FTDI Basic Breakout - 5V





This is the newest revision of our FTDI Basic. We now use 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.
