Description
The Spark Core is an Arduino-compatible, Wi-Fi enabled, cloud-powered development platform that makes creating internet-connected hardware a breeze.
This shield is essentially an adapter that allows the user to connect Arduino compatible shields to the Spark Core. There are two functions that this shield performs: pin mapping of the Spark Core to the Arduino pin layout and voltage translation of 3.3V to/from 5V.
We use Texas Instruments TXB0108PWR to do the voltage translation in between Spark Core’s 3.3V logic level and Arduino’s 5V logic.
Due to the limited number of pin to function combinations, we have only mapped three analog channels A0, A1 and A2. Unlike other IO pins, the analog pins are rated at only a max of 3.3V and NOT 5.0V. Please remember NOT to exceed this voltage at anytime.
The shield has an onboard voltage regulator and can be powered from 7V to 15V DC. You could also power it via the USB plug on the Spark Core alone but the current would be limited to 500mA.
The pictures shows a robot shield interfaced with the Spark Core via the Shield Shield.
Specifications
- Operating voltage: 7 to 15V DC
- Current consumption: without the core plugged in 7mA at 9V DC and 150mA with the Core.
- Dimensions: 3.79” x 2.1”
- Weight: 40g
Pin Mapping
IMPORTANT: The Shield Shield does not map the Spark Core pins to like-numbered pins on the Arduino. In other words, D0 on the Spark Core is not the same as D0 on the Arduino. Please review the pin mapping table to the right and plan accordingly.

描述
星火核心是一個Arduino兼容，支持Wi-Fi，雲驅動的開發平台，使創建互聯網連接的硬件變得輕而易舉。
此屏蔽實質上是一個適配器，它允許用戶Arduino的兼容屏蔽連接到火花核心。有跡象表明，這種屏蔽執行兩個功能：星火核心3.3V至/從5V的Arduino的引腳佈局和電壓轉換的引腳映射。
我們使用德州儀器TXB0108PWR做電壓轉換的核心星火的3.3V邏輯電平的Arduino的5V邏輯之間。
由於有限數量銷起作用的組合，我們只映射三個模擬通道A0，A1和A2中。不像其他的IO引腳，模擬引腳僅3.3V和5.0V不是一個最大額定。 請切記不要在任何時候超過這個電壓。
該罩具有一個板載電壓調節器，並且可以從7V供電，以15V的直流。您也可以通過USB插頭電源它星火核獨顯，但目前將被限制為500mA。

產品規格
- 工作電壓：7〜15V DC
- 消耗電流：在沒有9V DC在7毫安插入的核心到150mA的核心。
- 尺寸：3.79“×2.1”
- 重量：40g
引腳映射
重要提示：盾牌不會映射星火核心引腳喜歡編號Arduino上的引腳。換句話說，D0的火花Core是不一樣D0 Arduino上的。請查看引腳映射表的權利和相應的計劃。
