描述

Sparkfun FTDI Basic Breakout – 3V FT232RL 晶片 Sparkfun 原裝進口

Sparkfun FTDI Basic Breakout 是 Sparkfun FTDI Basic 的最新版本。Sparkfun 現在在底部使用SMD 6引腳接頭，這使得它更小，更緊湊。功能保持不變。這是FTDI FT232RL USB到串行IC的基本分線板。該電路板的引腳配合FTDI電纜與Arduino官方工作並 Clone 3.3V Arduino電路板。它也可以用於一般的串行應用程序。這塊板的主要區別在於它帶出了DTR引腳，而不是FTDI電纜的RTS引腳。DTR引腳允許Arduino目標在下載新草圖時自動重置。這是一個非常不錯的功能，並允許下載草圖而無需點擊重置按鈕。該電路板將自動復位任何帶有復位引腳引出到6引腳連接器的Arduino電路板。

• 標記為BLK和GRN的引腳對應於FTDI電纜上的彩色電線。FTDI電纜上的黑線是GND，綠色是CTS。使用這些BLK和GRN引腳將FTDI基板與Arduino目標對齊。
• 該板具有TX和RX LED，使其通過FTDI電纜使用會更好一些。實際上，您可以在LED上看到串行通信，以驗證該板是否正常工作。
• 該電路板旨在降低Arduino開發的成本並提高易用性（自動重設功能！）。我們的Arduino Pro板和LilyPads使用這種類型的連接器。

SparkFun FTDI Basic Breakout – 3.3V

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 3.3V 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 Mini-B 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 and LilyPad boards use this type of connector.
