The Adafruit Feather nRF52 Pro is another Bluetooth Low Energy board for advanced projects and users who want to use a fully open source Bluetooth Low Energy 5.0 stack. It has a native-Bluetooth chip, the nRF52832, as well as built in USB Serial and battery charging! We have other boards in the Feather family, check'em out here.
該Adafruit的羽毛nRF52臨是另一個藍牙低能源局的高級項目和誰想要使用的用戶完全開源的低功耗藍牙5.0堆棧。它具有本地藍牙芯片nRF52832，以及內置的USB串口和電池充電功能！ 我們在Feather家族中還有其他董事會，請在此處查看。
This is a special Feather - unlike the rest of the Feather family, this board is not for use with Arduino IDE. Instead, it is for use with Mynewt only! We have programmed it with the Mynewt bootloader and updated the hardware to add an SWD connector and an additional DFU button.If you want to use the nRF52 with Arduino IDE please check out the Bluefruit nRF52 Feather which works out-of-the-box with our Arduino board support package. This Feather is for advanced users only, you will be interacting with the Mynewt RTOS rather than Arduino, and you cannot easily go back-and-forth without an SWD programmer.
這是一種特殊的Feather-與Feather系列的其他產品不同，該開發板不適用於Arduino IDE。而是僅與Mynewt一起使用！我們已使用Mynewt引導加載程序對其進行了編程，並更新了硬件以添加SWD連接器和附加的DFU按鈕。如果您想將nRF52與Arduino IDE結合使用，請查看Bluefruit nRF52 Feather，它可以與我們的Arduino開發板支持包一起使用。 該功能僅適用於高級用戶，您將與Mynewt RTOS而不是與Arduino進行交互，並且如果沒有SWD程序員，您將無法輕鬆地往返。
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
At this point, the tools that Mynewt relies on are really aimed at running on a POSIX-type system (Linux, OS X, Mingw etc.) Windows users can also make use of the Docker container available on the Mynewt website.
此時，Mynewt所依賴的工具實際上旨在在POSIX類型的系統（Linux，OS X，Mingw等）上運行。Windows用戶還可以使用Mynewt網站上可用的Docker容器

This chip has twice the flash, SRAM and performance of the earlier nRF51-based modules, and can do a lot of heavy lifting. That extra processing power and memory mean you can now run an RTOS for fast development of complex projects. This board was designed to work with the Apache Mynewt operating system, which is released by the Apache Foundation under the permissive and commercial-friendly Apache license. Apache Mynewt includes a number of professionally written networking stacks (BLE 5.0, OIC/OCF, etc.), development tools, and professional project management features like a secure bootloader that allows you to cryptographically sign firmware images and verify them during device updates.
該芯片的閃存，SRAM和性能是早期基於nRF51的模塊的兩倍，並且可以完成很多繁重的工作。額外的處理能力和內存意味著您現在可以運行RTOS來快速開發複雜項目。該評估板旨在與Apache Mynewt操作系統配合使用，該操作系統由Apache Foundation根據許可且對商業友好的Apache許可發布。Apache Mynewt包括許多專業編寫的網絡堆棧（BLE 5.0，OIC / OCF等），開發工具以及專業的項目管理功能，例如安全的引導加載程序，可讓您對設備映像進行加密簽名並在設備更新期間對其進行驗證。
The Adafruit Feather nRF52 Pro ships pre-programmed with the Mynewt serial bootloader that allows you to flash firmware to the device directly from the command-line using the on-board USB Serial converter and the 'newtmgr' tool, so you can get started right away with no additional hardware required. For more advanced debugging, however, you can use a Segger J-Link and the on-board SWD debug connector, which gives you access to a more powerful set of development tools and options.
Adafruit Feather nRF52 Pro出廠時已使用Mynewt串行引導加載程序進行了預編程，它允許您使用板載USB串行轉換器和“ newtmgr”工具直接從命令行將固件閃存到設備，因此您可以開始正確使用無需額外的硬件。但是，對於更高級的調試，您可以使用Segger J-Link和板載SWD調試連接器，它使您可以訪問功能更強大的一組開發工具和選項。
We also have a custom Mynewt Manager application that we've written for iOS that allows you to perform over the air firmware updates, and get live updates of the tasks running in the task manager, or to see any statistics generated by the internal reporting systems that are part of the OS.
我們還有一個專為iOS編寫的自定義Mynewt Manager應用程序，可讓您執行空中固件更新，獲取任務管理器中正在運行的任務的實時更新，或查看內部報告系統生成的任何統計信息是操作系統的一部分。

Bluetooth Low Energy is the hottest new low-power, 2.4GHz spectrum wireless protocol. In particular, its 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, 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，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】
The nRF52 Pro uses 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 - example 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.
nRF52 Pro使用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-提供了示例代碼！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 the Apache Mynewt operating system, 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！得益於Apache Mynewt操作系統，您可以完全控制設備的行為，包括定義和操作自己的 GATT服務和特徵的能力，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
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. 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。該數據可通過BLE讀取並由nRF52微控制器直接處理
Comes fully assembled and tested, with a USB Serial bootloader that lets you quickly use it from the command line. 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串行引導加載程序，經過完全組裝和測試，可讓您從命令行快速使用它。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！）

【版本記錄】：
截至2018年7月30日，我們對nRF52進行了較小的修訂，以通過USB而非板載穩壓器為CP2104自供電。這沒有功能上的變化，但是改善了未連接USB時的功耗。而且我們已經更新到修訂版的矽2的nRF52832
As of July 30, 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. And we've updated to rev 2 of the silicon for the nRF52832
