¬†Once you have the Arduino all figured out it is time to set your sights on the¬†Internet¬†Of¬†Things, machine learning and AI.¬† To start off quickly and easily use the WioTerminal as an IoT central station, you can fully automate your house or business and use all kinds of wireless technologies to control the “things” at home (or at work if you so wish) from anywhere in the world. It works perfectly with the Arduino IDE and you will feel “at home” if you used the Arduino programming environment in the past.

This Seeed Wio Terminal, although super easy to program and use, it is not recommended for beginners. Rather start with an Arduino starter kit to learn the basics first.

The WIO terminal will quickly become your central IOT station from where you can hook up many devices and sensors (directly or wirelessly), all controlled from this great looking and powerful WIO terminal. While talking about cosmetics, the screen is nice and big with a navigation joystick so you can scroll through many menus you created or display sensor values that can easily be seen from a distance. 

 

When you go IoT, Edge computing or Artificial Intelligence you need much more processing power, lots more memory and definitely WiFi and Bluetooth. You need storage of your data on the cloud or on SD card and quite a few things that you will not find on basic development boards. This WIO terminal has it all and much more.

This unit is powered by the ATSAMD51 microcontroller with ARM Cortex-M4F core running at 120MHz! Best of all, you can program it with the Arduino IDE or MicroPhython if you wish. It is even compatible with Raspberry Pi, at the back is a full set of headers that allows you to use this device as a Pi Hat. Lots of tutorials are also available for ArduPi and Visual basic programming for the Seeed Wio Terminal. 

Use this device as an IOT device or for edge computing as to name only a few applications. Game programming is at your fingertips too and with the accelerometer, you can do quite a few very cool game-like programs. It can run as a USB host or client and you can use your USB devices like that favourite game controller with ease with this terminal. Great for games but also for many other things like using a mouse to navigate menus.

The one thing about the SEEED product range that always impresses me is their detailed product documentation. This product is not any different, it comes with many projects and a full course on how to use the WIO terminal. Simply head over to their Wiki page for stacks of information, examples, libraries and projects. Lots of projects are also available on hackster.io like this HQTT project for home automation.

It supports both Bluetooth and Wi-Fi providing the backbone for IoT projects. The Wio Terminal itself is equipped with a:

  • 2.4‚ÄĚ LCD Screen
  • onboard IMU(LIS3DHTR)
  • Microphone
  • Buzzer
  • microSD card slot
  • Light sensor
  • Infrared Emitter(IR 940nm)
  • Two multifunctional Grove ports
  • 40 Raspberry pi compatible pin GPIO for more add-ons.

Being a SEEED product it supports the full range of SEEED Groove boards. Of cause you are not locked into using these amazing boards, at the back is 40 GPIO pins you can use to plugin other sensors and modules. What is very cleverly done is that the IO ports also fits perfectly on a Raspberry Pi so you can use the WIO terminal as a PI Hat.

In Conclusion.

There is just too much this unit can do to cover in this block post. Best is to go to the Seeed studio wiki page. But be prepared, you will have more data at your fingertips that will take more than an evening to go through. The free course will probably take you a couple of days to complete but again, as expected from SEEED, you will fly through even the difficult sections with ease. They have the tendency to create hardware that just works without hours of fault-finding and frustration.
