RedBear DUO – Wi-Fi + BLE IoT Board 物聯網開發板 產品介紹

RedBear 公司所推出、尺寸只有姆指一般大的 Duo 開發板 ,能夠簡化物聯網裝置的開發流程,Duo提供了多種開發者需要的功能,支援Wi-Fi無線網 路、BLE低功耗藍牙等傳輸規範,還能夠支援RBLink擴充子板,讓開發者可以輕鬆擴充各種感應器以及功能模組,嘗試動手打造各種試作品或是成品。

RedBear 先前曾推出第一款Arduino用的低功耗藍牙擴充板,過去也推出多款改版產品,在累積了一定IoT領域的經驗之後,RedBear這次推出了自有品牌的Duo開發板。

Duo同時支援Wi-Fi無線網路、BLE低功耗藍牙等傳輸規範,由於許多物聯網裝置受到成本與耗電量因素的限制,會採用低功耗藍牙規範做為傳輸、控制方式,Duo當然不會忽略這個考量,使用者可以使用智慧型手機等裝置遙控Duo,設計各種互動式應用功能,例如可以透過智慧型手機操作的遙控門鎖。但是當需要將遙控距離拉長的時候,則可以讓Duo透過無線網路連上網,如此一來使用者就可以在任何地方透過網路連回Duo,從遠端下達遙控指令。

另一方面,Duo也與Particle合作,提供終身免費的建雲端服務功能,使用者只需要進行簡單設定後,Duo就能使用Particle所提供的多種工具與套件,讓Duo的功能更加多元。

Introduction

The Duo is a thumb-size development board designed to simplify the process of building Internet of Things (IoT) products. The Duo provides everything you need—Wi-Fi, BLE and a powerful Cloud backend, all in a compact form factor that makes it ideal for your first prototype, a finished product, and everything in between.

We’re also introducing the RBLink, an expansion board for the Duo that allows you to attach additional sensors and modules without any soldering. You’ll have all the tools you need to get your prototype up and running in no time.

Wi-Fi + BLE

The Duo is your Bluetooth gateway to the Internet of Things. It allows you to communicate with your projects both over the web and with your phone, enabling a wide range of cool interactions. Would you like to build a front door lock that can be opened using a phone and whose settings can be changed wirelessly to give access to additional people? Maybe connected lights that turn on as your phone comes in range but can also be controlled when you’re miles away from home? Wi-Fi + BLE also means you can do make your wearable products extra interesting by adding things like beacons and data collection. Oh and robots! Whether you’re in the same room or halfway around the world, the Duo gives you all the connectivity you’ll need to control, interact, monitor, and play with your awesome new creations.

 

Duo is a thumb-size development board made to simplify the building process of Internet of Things (IoT) products. Everything you need is built into the Duo. It contains WiFi, BLE and Cloud, all in a compact form factor that makes it ideal for your first prototype, a finished product, and everything in between.

With the help of RB Link, a RedBear expansion board, you can attach add-on modules without any soldering at all. You can get your prototype up and running in no time. You can buy Grove Starter Kit for Photon to develop projects.
