Adafruit原廠 Feather nRF52 Bluefruit LE - nRF52832 (ada3406)
Technical Details
［Revision History］版本記錄：
- As of March 16, 2018 We've done a minor revision to the nRF52 to self-power the CP2104 from USB not from the onboard regulator. This has no functional change but has improved the power consumption when not connected to USB
截至2018年3月16日我們對 nRF52 進行了小幅修訂，以從 USB 而不是機載調節器中自供電 CP2104。這沒有功能變化，但在未連接到 USB 時提高了功耗
- As of June 27, 2018 We've updated to rev 2 of the silicon for the nRF52832
截至2018年6月27日我們已更新為nRF52832的矽轉速2
Description
The Adafruit Feather nRF52 Bluefruit is another easy-to-use all-in-one Bluetooth Low Energy board, with a native-Bluetooth chip, the nRF52832! It's our take on an 'all-in-one' Arduino-compatible + Bluetooth Low Energy with built in USB and battery charging. We have other boards in the Feather family, check'em out here.
該Adafruit的羽毛nRF52 Bluefruit是另一種易於使用的所有功能於一身的藍牙低功耗主板，用本機藍牙芯片，該nRF52832！這是我們對“兼容多用”的Arduino兼容+內置低功耗USB和電池充電功能的低功耗藍牙技術的看法。我們在Feather家族中還有其他董事會，請在此處查看。
This chip has twice the flash, SRAM and performance of the earlier nRF51-based Bluefruit modules. Best of all, it has Arduino IDE support so there is no 'helper' chip like the ATmega32u4 or ATSAMD21. Instead, this chip is programmed directly! It's got tons of awesome peripherals: plenty of GPIO, analog inputs, PWM, timers, etc. Leaving out the extra microcontroller means the price, complexity and power-usage are all lower/better. It allows you to run code directly on the nRF52832, straight from the Arduino IDE as you would with any other MCU or Arduino compatible device. A single MCU means better performance, lower overall power consumption, and lower production costs if you ever want to design your own hardware based on your Bluefruit nRF52 Feather project!
該芯片的閃存，SRAM和性能是早期基於nRF51的Bluefruit模塊的兩倍。最棒的是，它具有Arduino IDE支持，因此沒有像ATmega32u4或ATSAMD21這樣的“輔助”芯片。而是直接對該芯片進行編程！那裡有很多很棒的外設：大量的GPIO，模擬輸入，PWM，計時器等。省去了額外的微控制器意味著價格，複雜性和功耗都更低/更好。它使您可以直接在Arduino IDE上直接在nRF52832上運行代碼，就像使用任何其他MCU或Arduino兼容設備一樣。如果您想基於Bluefruit nRF52 Feather項目設計自己的硬件，則單個MCU意味著更好的性能，更低的總體功耗和更低的生產成本！
We have quite a few BTLE-capable Feathers (it's a popular protocol!) so check out our BT Feather guide for some comparison information.
我們有許多支持BTLE的羽毛（這是一個受歡迎的協議！），因此請查看我們的BT羽毛指南以獲取一些比較信息。
We pre-programed the chip with an auto-resetting bootloader so you can upload quickly in the Arduino IDE with no button-pressing. Want to program the chip directly? You can use our command line tools with your favorite editor and toolchain. If you want to use an SWD programmer/debugger (for even more advanced usage), pick up an SWD box header to solder into the spots provided.
我們使用自動重置的引導加載程序對芯片進行了預編程，因此您無需按下按鈕即可在Arduino IDE中快速上載。是否要直接對芯片進行編程？您可以將我們的命令行工具與您喜歡的編輯器和工具鏈一起使用。如果要使用SWD編程器/調試器（甚至更高級的用法），請拾取SWD盒接頭，以焊接到提供的位置。
Best of all, we've done all the heavy lifting of getting the low level BLE stack into shape so you can focus on your project from day one! The example code works great with our existing iOS and Android app.
最重要的是，我們已經完成了將低級BLE堆棧成型的所有繁重工作，因此您可以從第一天開始專注於您的項目！該示例代碼可與我們現有的iOS和Android應用完美配合。

Bluetooth Low Energy is the hottest new low-power, 2.4GHz spectrum wireless protocol. In particular, it's the only wireless protocol that you can use with iOS without needing special certification, and it's supported by all modern smart phones. This makes it excellent for use in portable projects that will make use of an iOS or Android phone or tablet. It also is supported in Mac OS X and Windows 8+.
低功耗藍牙是最熱門的新型低功耗2.4GHz頻譜無線協議。特別是，它是唯一可以與iOS一起使用而無需特殊認證的無線協議，並且所有現代智能手機均支持該協議。這使其非常適合在將使用iOS或Android手機或平板電腦的便攜式項目中使用。Mac OS X和Windows 8+也支持它。
To make it easy to use for portable projects, we added a connector for any of our 3.7V Lithium polymer batteries and built in battery charging. You don't need a battery because it will run just fine straight from the micro USB connector. But, if you do have a battery, you can take it on the go, then plug in the USB to recharge. The Feather will automatically switch over to USB power when it's available. We also tied the battery thru a divider to an analog pin, so you can measure and monitor the battery voltage to detect when you need a recharge.
為了便於在便攜式項目中使用，我們為任何3.7V鋰聚合物電池添加了一個連接器，並內置了電池充電功能。您不需要電池，因為它可以直接從Micro USB連接器正常運行。但是，如果您有電池，可以隨身攜帶，然後插入USB進行充電。Feather可用時將自動切換到USB電源。我們還將電池通過分壓器連接至模擬引腳，因此您可以測量和監視電池電壓，以檢測何時需要充電。
The Power of Bluefruit LE 力量
The Bluefruit LE module is an nRF52832 chipset from Nordic, which can be used as both a main microcontroller and a bluetooth low energy interface. For most people, they'll be very happy to use the standard Nordic UART RX/TX connection profile - code is provided! In this profile, the Bluefruit acts as a data pipe, that can 'transparently' transmit back and forth from your iOS or Android device. You can use our iOS App or Android App, or write your own to communicate with the UART service.
Bluefruit LE模塊是Nordic的nRF52832芯片組，既可以用作主微控制器又可以用作藍牙低功耗接口。對於大多數人來說，他們將很高興使用標準的Nordic UART RX / TX連接配置文件-提供了代碼！在此配置文件中，Bluefruit充當數據管道，可以“透明”地從您的iOS或Android設備來回傳輸。您可以使用我們的 iOS應用程序 或 Android應用程序，也可以 編寫自己的應用程序與UART服務進行通信。
The board is capable of much more than just sending strings over the air! Thanks to an Arduino wrapper library, you have full control over how the device behaves, including the ability to define and manipulate your own GATT Services and Characteristics, or change the way that the device advertises itself for other Bluetooth Low Energy devices to see.
該板不僅具有無線發送字符串的功能，還具有更多的功能！多虧了Arduino包裝庫，您可以完全控制設備的行為，包括定義和操作自己的 GATT服務和特性的能力，或者更改設備宣傳自己的方式以供其他低功耗藍牙設備查看的能力。
Use the Bluefruit App to get your project started
使用Bluefruit App啟動您的項目專案
Using our Bluefruit iOS App or Android App, you can quickly get your project prototyped by using your iOS or Android phone/tablet as a controller. We have a color picker, quaternion/accelerometer/gyro/magnetometer or location (GPS), and an 8-button control game pad. This data can be read over BLE and processed directly by the nRF52 microcontroller
使用我們的Bluefruit iOS App 或 Android App，您可以使用iOS或Android手機/平板電腦作為控制器來快速獲得項目原型。我們有一個 顏色選擇器，四元數/加速度計/陀螺儀/磁力計或位置（GPS）和一個8鍵 控制遊戲手柄。該數據可通過BLE讀取並由nRF52微控制器直接處理
You can do a lot more too! 你也可以做得更多！
- The Bluefruit can also act like an HID Keyboard (for devices that support BLE HID)
藍果也可以像HID鍵盤一樣（用於支援 BLE HID 的裝置 ） - Can become a BLE Heart Rate Monitor (a standard profile for BLE) - you just need to add the pulse-detection circuitry
可以成為 BLE 心率監測器（BLE的標準配置文件）-您只需要添加脈衝檢測電路 - Turn it into a Beacon, the Google standard for Bluetooth LE beacons. Just power it and the 'Friend will bleep out a URL to any nearby devices with the nRF Beacon app installed.
將其變成Beacon（藍牙LE信標的Google標準），只需打開電源，“朋友”就會在安裝了nRF Beacon應用的情況下發出指向附近任何設備的URL。 - Built in over-the-air bootloading capability. Use any Android or iOS device to get updates and install them via the Nordic OTA app (or the Adafruit app). This will update the native code on the BLE module, and is an alternative to the USB-serial bootloader
內置無線引導加載功能。使用任何Android或iOS設備獲取更新並通過Nordic OTA應用程序（或Adafruit應用程序）進行安裝。這將更新BLE模塊上的本機代碼，並且是USB串行引導程序的替代方法
Comes fully assembled and tested, with a USB bootloader that lets you quickly use it with the Arduino IDE. We also toss in some header so you can solder it in and plug into a solderless breadboard. Lipoly battery and MicroUSB cable not included (but we do have lots of options in the shop if you'd like!)
帶有USB引導加載程序，經過完全組裝和測試，可讓您與Arduino IDE快速配合使用。我們還會折騰一些接頭，以便您可以將其焊接並插入無焊麵包板。 不包括Lipoly電池和MicroUSB電纜 （但如果您願意，我們在商店中確實有很多選擇！）
