The new Wio Node was born with most of the features of its elder brother:

  • An ESP8266 based open-source Wi-Fi development board
  • Supports Plug-n-Play Groves
  • Visual Configuration
  • OTA (Over-The-Air) Firmware Updates
  • RESTful APIs
  • IFTTT Application
  • Android & iOS APPs

This little guy is cheaper, smaller and lighter in weight.

Even though the compact design only has two Grove connectors, it still offers as many as 2 Digital I/O, 1 Analog Input, 1 UART and 2 I2C interfaces to communicate with up to 42 (and more to come) Grove modules. Setting up an IoT device with Wio Node is piece of cake as all the Grove sensor/actuator modules can be visually configured to RESTful APIs on your mobile APPs, and the physical circuit connections does not involve any bread boarding, soldering, or wire jumpers. Once you finish updating the firmware over-the-air (OTA), you’ll find out it only takes you 5 minutes to build an IoT application with the Wio Node.

Owing to its low-cost, easy-to-use and compact design, Wio Node can be used to build an IoT system where a large amount of ‘things’ are required to be connected to the internet. Seeed has provided detailed instructions and rich tutorials at http://iot.seeed.cc/ to help you getting started with your Wio Node easily and quickly. You can also find out more interesting stuff at the Wio Community, where all the Wio fans gather to share their ideas and experiences.
