Description

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: 

• Sense and tag the Real-World data with over 300 Groves created by Seeed
• Easily build your TinyML applications with Edge Impulse
• Use 100% open-source Hardware in a pythonic way
• Build your program interpreter starting from 90% with an LCD screen and compact enclosure

Compatible with Arduino and Micropython, Wio Terminal is an ATSAMD51-based microcontroller with wireless connectivity powered by Realtek RTL8720DN. Currently, wireless connectivity is only supported by Arduino. Its CPU speed runs at 120MHz (Boost up to 200MHz). Realtek RTL8720DN chip supports both Bluetooth and Wi-Fi providing the backbone for IoT projects. The Wio Terminal itself is equipped with a 2.4” LCD Screen, onboard IMU(LIS3DHTR), microphone, buzzer, microSD card slot, light sensor, and infrared emitter(IR 940nm). 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.

• Wio Terminal + Grove = IoT System
• Wio Terminal + Raspberry Pi = Edge Computing System
• Wio Terminal + Customized add-ons = Handheld devices or endless possibilities!
