描述
正廠 SparkFun Arduino Pro Mini 328 – 3.3V/8MHz 美國 SparkFun 原裝進口
這是Arduino Pro Mini , SparkFun對Arduino的最小設計方法。這是一個運行8MHz引導程序的3.3V Arduino。Arduino Pro Mini不附帶連接器，因此您可以用任何方向焊接任何連接器或導線。我們建議Arduino用戶首次使用Uno R3。這是一個偉大的董事會，將讓你快速運行。Arduino Pro系列適用於那些了解系統電壓（3.3V），連接器不足和USB關閉的限制的用戶。
我們真的想盡量減少Arduino的成本。為了做到這一點，我們使用了所有的SMD元件，使它成為兩層，等等。該板直接連接到FTDI Basic Breakout板，並支持自動復位。Arduino Pro Mini也可以使用FTDI電纜，但FTDI電纜不能引出DTR引腳，所以自動復位功能將不起作用。有一個電壓調節器，所以它可以接受高達12VDC的電壓。如果您向電路板提供未經調節的電源，請確保連接到VCC上的“RAW”引腳。

原廠技術文件與範例
Arduino Pro Mini 328 – 3.3V/8MHz
It’s blue! It’s thin! It’s the Arduino Pro Mini! SparkFun’s minimal design approach to Arduino. This is a 3.3V Arduino running the 8MHz bootloader. Arduino Pro Mini does not come with connectors populated so that you can solder in any connector or wire with any orientation you need. We recommend first time Arduino users start with the Uno R3. It’s a great board that will get you up and running quickly. The Arduino Pro series is meant for users that understand the limitations of system voltage (3.3V), lack of connectors, and USB off board. We really wanted to minimize the cost of an Arduino. In order to accomplish this we used all SMD components, made it two layer, etc. This board connects directly to the FTDI Basic Breakout board and supports auto-reset. The Arduino Pro Mini also works with the FTDI cable but the FTDI cable does not bring out the DTR pin so the auto-reset feature will not work. There is a voltage regulator on board so it can accept voltage up to 12VDC. If you’re supplying unregulated power to the board, be sure to connect to the “RAW” pin on not VCC. The latest and greatest version of this board breaks out the ADC6 and ADC7 pins as well as adds footprints for optional I2C pull-up resistors! We also took the opportunity to slap it with the OSHW logo. Can’t decide which Arduino is right for you? Arduino buying guide! Note: A portion of this sale is given back to Arduino LLC to help fund continued development of new tools and new IDE features.
