商品說明

Arduino Pro Mini 328 – 3.3V/8MHz

這是運行8MHz引導加載程序的3.3V Arduino。 Arduino Pro Mini沒有配備連接器，因此您可以使用任何方向焊接任何連接器或電線。我們建議Arduino用戶第一次使用Uno R3。這是一個很棒的板，可以幫助您快速啟動和運行。 Arduino Pro系列適用於了解系統電壓（3.3V），連接器缺失和USB板外的局限性的用戶。

我們真的想最大限度地降低Arduino的成本。為了實現這一點，我們使用了所有SMD組件，使其成為兩層等。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電纜不會帶出DTR引腳，因此自動復位功能不起作用。板上有一個電壓調節器，因此它可以接受高達12VDC的電壓。如果您向電路板提供未經調節的電源，請務必連接到非VCC上的“RAW”引腳。

該板的最新版本突破了ADC6和ADC7引腳，並增加了可選I2C上拉電阻的佔位面積！

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.
