Wio Terminal is an ATSAMD51-based microcontroller with both Bluetooth and Wi-Fi Wireless connectivity powered by Realtek RTL8720DN, compatible with Arduino and MicroPython. Currently, wireless connectivity is only supported by Arduino. More than just a single embedded functional module, Wio Terminal itself is integrated with a 2.4” LCD Screen, onboard IMU(LIS3DHTR), microphone, buzzer, microSD card slot, light sensor, infrared emitter(IR 940nm).On top of that, it also has two multifunctional Grove ports for Grove Ecosystem and 40 Raspberry pi compatible pin GPIO for more add-ons. All of these practical add-ons are carefully housed in a compact enclosure, making it an efficient and product-ready product. Equipped with Raspberry Pi 40-pin GPIO, it can be mounted to a Raspberry Pi as a slave device.

Key Features

  • Powerful MCU: Microchip ATSAMD51P19 with ARM Cortex-M4F core running at 120MHz

  • Reliable Wireless Connectivity: Equipped with Realtek RTL8720DN, dual-band 2.4Ghz / 5Ghz Wi-Fi

  • Complete system equipped with Screen + Development Board + Input/Output Interface + Enclosure

  • Highly Integrated Design: 2.4” LCD Screen, MCU, IMU, WIFI, BT, and more practical add-ons housed in a compact enclosure with built-in magnets & mounting holes allows you to easily set up your IoT project

  • Raspberry Pi 40-pin Compatible GPIO enables installation as a peripheral to the Raspberry Pi

  • External onboard multi-functional Grove ports: Compatible with over 300 Plug&Play Grove modules to explore with IoT

  • USB OTG Support: can act as a USB host (reads data or signals from a mouse, keyboard, MIDI device, 3D printer, etc.) or USB client (emulates a mouse, keyboard, or MIDI device to a host PC).

  • Support Arduino, CircuitPython, Micropython, ArduPy(What is ArduPy?), AT Firmware, Visual Studio Code

  • TELEC certificated


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. 

Meet our new member: Wio Terminal is compatible with Arduino and Micropython, built with an ATSAMD51 microcontroller with wireless connectivity supported by Realtek RTL8720DN. 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 is Highly Integrated with a 2.4” LCD Screen, there is an onboard IMU(LIS3DHTR), microphone, buzzer, microSD card slot, light sensor, and infrared emitter(IR 940nm). 

There are built-in magnets and two mounting holes on the well-designed enclosure, allowing you to set up your IoT project without hassle.

On top of that, it also has two multifunctional Grove ports for connecting with over 300 modules and Raspberry Pi 40-pin compatible GPIO for tons of Pi HAT add-ons, which means there are endless IoT possibilities you can create with this tiny device! 

With Wio Terminal, you can: 

  • Sense and tag the Real-World data with over 300 Groves created by Seeed and visualize through Azure IoT Central Platform to create an end-to-end IoT project

  • Use 100% open-source Hardware in a pythonic way

  • Build your program interpreter starting from 90% with an LCD screen and compact enclosure

  • Create embedded GUI with easy-to-use graphical elements and beautiful visualized editing tools.

Hello World of AI

Powered by TinyML and Wio Terminal, Paired up with Edge Impulse and Azure IoT, your will find an easier way to navigate the ever-changing landscape of their AIoT journey. 

Connecting the Wio Terminal to Azure IoT Central

Wio Terminal is an Azure-certified device, not only can the artificial nose sense and tag the scents you want to know in the air, but everything can be analyzed and visualized in real-time through Azure IoT Central. More importantly, you can automatically trigger rules when, for example, a bad smell is being detected, therefore allowing the nose to be much smarter than if it were just a standalone, offline, device.

    Even my 12-year-old son can get started quickly
    Got my new toy today!! Looked through the wiki and tried a few demos. I have to say that Seeed has done a good job writing so many well-organized tutorials and documents, and even my 12-year-old son can get started quickly.
    Question: will you consider adding a touch screen if you are going to make a new version? It will make much more fun!
