Wio Node

Wio Node is an ESP8266 SoC based open-source Wi-Fi development board and associated platform to create IoT applications by virtualizing plug-n-play modules to RESTful APIs with mobile Apps. Wio Link is designed to simplify your IoT development, aims to make it easy to develop Internet of Things products and services. Using the Wio Link, developers are able to build IoT applications with no hardware programming, no breadboard, no jumper wires, and no soldering. Users can build IoT applications in three steps in about five minutes.

Compared to Wio Link, it is smaller and cheaper. This product is suitable for application scenarios where a large number of sensors collect data or places where only a simple wireless input/output is required.

The ecosystem consists of Open Hardware Wio Node board, Open Source Wio Link Mobile App and Open Source IoT Server implementation. The board provides Grove connectors to easily interface with a variety of Grove modules. It also has on-chip power management for charging LiPo battery. The Mobile App has all the features to configure the board, to update firmware and to test/interact with application running on the board. The Server provides various infrastructure to connect the board to internet.

Connecting LiPo Battery

Note: Battery needs to be bought separately. Use Bazaar site to find suitable battery options available.

Get started

Let us build a very basic example with Wio Node platform. We will try to toggle one digital output pin of Wio Node board using "Generic Digital Output" API.

Step 1: Install Android/iOS App

You need to install the Wio Link App to manage and configure your Wio Node devices.

Download the Android or iOS App and install.

Note: Make sure your Android OS version is 4.1 or advanced, iOS version is 7 or advanced.

Step 2: Create your Account

If you use the Android/iOS App for the first time, you need to sign up for an account.

1. Open Wio Link App

2. Click Sign-Up and Create a new user account

Note: We provide two server options -- China mainland and International. If you are from Mainland China, select China server. Others, select International server. Selecting the appropriate server based on your location will speed up your development.

Step3: Connect Wio Node WiFi AP

Step 4: Virtually interconnect modules with Wio Node

Step 5: Download firmware

Step 6: Test application using APIs

The LED or any other digital output actuator will toggle based on the Digital Value being sent.
