ARDUINO YUN REV 2 開發板 YUN R2 雲 支援乙太網路與 WIFI 連線

Arduino Yun Rev 2 是新系列Arduino 開發板的新成員,該板結合了Linux的功能和Arduino的特性簡單性。它結合了Leonardo模型晶片(ATMega32U4)和運行基於OpenWRT的Linux發行版Linino的SOC(片上系統)模組。最有趣的功能之一是它支持有線以太網和Wifi網絡。Arduino芯片已連接到Linux模組,因此它們之間的通信非常容易,並將繁重的過程委派給板載的Linux機器。

Arduino Yun Rev 2 連接性:

它具有兩個網絡連接。一個10/100 mbps以太網網絡和另一個可以作為客戶端或接入點安裝的Wifi(IEEE 802.11 b / g / n,2.4GHz)。

處理器之間的連接:

為了將小型ATMega32U4與Linux模組進行通信,使用了Bridge庫,這使事情變得更加容易,並且由Arduino團隊直接提供支持。AR9331的串行端口通過針腳0和1連接到32U4的串行端口。AR9331的串行端口是對CLI控制台的訪問,該控制台允許啟動進程並直接從控制台檢索消息。默認情況下已經預先安裝了幾個文件系統管理和管理軟件包(包括Python解釋器),並且橋接庫還允許您使用同一系統安裝和啟動自己的應用程序。最有趣的優點之一是 Arduino Yun Rev 2 板(在32U4側)可以由Wifi通過Linux模組直接編程。

這是一塊可以讓你實現各種可能性的開發板子。還應注意,它具有MicroSD內存插槽,可讓您在其上存儲數據,例如網頁,日誌或我們需要的任何其他東西,從而進一步擴展了開發板的可能性。

ARDUINO YÚN REV 2

Arduino Yún Rev 2 is a Microcontroller Board based on the Microchip Technology ATmega32U4 8-bit Microcontroller and the Qualcomm Atheros AR9331 Processor. The Atheros Processor supports a Linux distribution based on OpenWrt named LininoOS. The board has built-in 802.3 10/100Mbit/s Ethernet and Wi-Fi® 802.11b/g/n 2.4GHz, making it ideal for connected IoT (Internet of Things) applications. Connection to a Wi-Fi or wired network is simple thanks to the YÚN Web Panel and the dedicated ”YunFirstConfig” sketch. Using the Yún Web Panel it is also possible to configure all the shield-related features and remotely upload sketches on the board connected to the shield. The Yún Rev 2 uses the Bridge library, extending the functionalities of the Microprocessor by using the computational power of the Linux processor on the board.

 

The Yún Rev 2 offers a space saving hoizontal Micro USB port and full USB 2.0 host, and a low-profile Ethernet 10/100 RJ45 port, designed to avoid potential short circuits when used with shields. Additional features include a microSD card slot, 20 digital input/output pins (7 of which can be used as PWM outputs and 12 as analog inputs), a 16MHz crystal oscillator, an ICSP header, 4 on-board status LEDs, and 3 reset buttons.

The hardware, software, and documentation of the Yún Rev 2 is freely available and open-source. This means that developers can learn exactly how it’s made and use its design as the starting point for their own projects.
