The Wio (Wireless Input and Output) platform (Wio Link, Wio Nodes,etc.) was first introduced to the world at the end of 2015 by Seeed.
Today a new Wio member is joining the family - Wio Terminal. Instead of being a single embedded functional module, Wio Terminal is more of a complete system equipped with Screen + Development Board + Input/Output Interface + Enclosure, making it an efficient and Product-Ready Product.
With Wio Terminal, you can:

On top of that, it also has two multifunctional Grove ports for Grove Ecosystem and Raspberry pi 40-pin compatible GPIO for more add-ons.
What is Grove?
No jumpers or soldering required, Grove makes it easier to connect, experiment, and simplify the prototyping process significantly. We have developed more than 300 Grove modules, covering a wide range of applications that can fulfill a variety of needs. Each one comes with clear documentation and demo code to help you get started quickly. Not only are these open hardware, but we also have open-source software.
