What's in the box
Product Description
Many of you might have a quick question: what does the “Wio” of Wio Terminal ever mean?
It is an abbreviation of “Wireless input and output”, a platform including hardware and software created by Seeed, aiming to simplify IoT development for makers. With the help of the Wio Family, even beginners can build his/her own IoT application within 5 minutes, no hardware programming, no breadboard, no jumper wires, no soldering.
Wio Terminal is the newest member of the Wio family. You must have noticed that it is quite different from its elder brothers, not a single embedded functional module but a simple and tiny device with highly-integrated design, packing multiple functions in a 72 x 57 x 12mm tiny but stylish enclosure. Together with its reliable wireless connectivity, setting up an IoT project is simpler than ever.
Highly Integrated Design
- MCU, LCD, WIFI, BT, IMU, Microphone, Buzzer, microSD Card, Configurable Buttons, Light Sensor, 5-Way Switch, Infrared Emitter (IR 940nm), Crypto-authentication Ready
- Well-designed enclosure with built-in magnets and two mounting holes, allowing you to set up your IoT project without hassle
Powerful MCU - Microchip ATSAMD51P19
- ARM Cortex-M4F core running at 120MHz (Boost up to 200MHz)
- 4 MB External Flash, 192 KB RAM
- Comprehensive Protocol Support
- SPI, I2C, I2S, ADC, DAC, PWM, UART(Serial)
Reliable Wireless Connectivity
- Powered by Realtek RTL8720DN
- Dual Band 2.4Ghz / 5Ghz Wi-Fi (802.11 a/b/g/n) & BLE 4.0 / BLE 5.0
Raspberry Pi 40-pin Compatible GPIO
Wio Terminal can be connected to Raspberry Pi through the 40 pins GPIO header or its USB Type-C connector.
It is integrated with onboard IMU(LIS3DHTR), microphone, light sensor, infrared emitter(IR 940nm) and two multi-functional Grove ports, which allows Wio Terminal to collect and send environmental data to Raspberry Pi for further process and analysis (i.e, machine learning) without hassle setting of hardware or software.
We will introduce a demo showing how to use Wio Terminal to read and display the system status of Raspberry Pi via USB serial. Please visit (seeedstudio.com/blog) for the demo.
In this demo, the 40 pin GPIO of Raspberry Pi is not taken and is available for use, which will be more convenient if there are any other Pi hats essential in your Raspberry Pi projects.
USB OTG Support
Accessible Devices(as USB-Host): Mouse, Keyboard, MIDI Devices, Xbox/PS Gaming Controllers, 3D Printers
Simulated Devices(as USB-Client): Mouse, Keyboard, MIDI Devices
Built-in Magnet and Mounting Hole for Easy Project Setup
We prepared two mounting holes on the back of the Wio Terminal, so it can be fixed into any place you like, simply using a screwdriver!
Built-in Magnet and Mounting Hole for Easy Project Setup
Four magnets are put into the enclosure. They are tiny but strong enough to attract metals. With the help of the built-in Magnets, you can easily attract your Wio Terminal to a blackboard or an iron door as a monitor or dashboard for your IoT project.
Imagine that you use Wio Terminal to make a smart home automation system: Decorate at your doorway, it displays the current temperature and humidity of your house, and open the air conditioners and lights automatically once you come back home. Your friends will consider it as some fancy new product you bought, not a DIY project!

There was a problem filtering reviews right now. Please try again later.
It’s a seriously capable little piece of kit.
However, this device has a problem with its USB interface. It sometimes refuses to work, and resets and reboots do nothing to fix the problem. I have to reboot the Mac to get the USB interface to work again, and sometimes that doesn't work.
I program dozens of devices through the Arduino IDE and have only seen this problem on an Adafruit product, which Adafruit later admitted as having a defect and issued a redesigned version. I suspect the same is happening here.
*Software Limitations*
Like many low cost open source hardware devices, this one is designed to be compatible with Arduino Studio and relatively code compatible with other devices, which is good. However like many other devices this is achieved by hacking existing open source Arduino libraries to work with the device.
In the case of Wio Terminal the libraries are an amalgamation of Arduino, AdaFruit, and Seeed code wrapped around the official Atmel libraries in a spaghettified mess designed to support multiple devices and chipsets, instead of providing each their own bespoke drivers.
On firing up the device for the first time, and writing a simple clear screen app to identify the baseline refresh rate I can expect from this device and screen, what did I discover?
Wio: 9 fps maximum just clearing the screen on a 200Mhz microprocessor. Are you kidding me?
For comparison a 16Mhz Arduino powering the same 9341 lcd screen achieves ~15 fps.
(Note: even with the Arduino the AdaFruit derived driver had appalling performance, 15 fps was achieved with a homegrown driver.)
With only two days using the device (and admittedly experience writing drivers for the 9341 lcd screen), I was able to write a driver pushing:
~40 fps rendering images to the screen (not just clearing).
Other peripheral drivers provided for the device appear to have similar issues, layering open source software, on top of other open source software, in an effort to make it work.
What does that mean for students and people just tinkering? Not much, the software works, it's just incredibly inefficient.
However for anyone attempting to fully utilize (or even moderately utilize) the device, know you will be writing all of your own drivers for the device's hardware. You need to understand this going into it.
*Good Hardware*
So what about the hardware? The embedded Cortex-M4 includes the optional floating point coprocessing core and can overclock to 200 MHz, which is really nice.
Hardware includes Wifi, Bluetooth, Flash RAM (4MB), MicroSD slot (up to 16GB), and more.
SPI channels can independently be clocked to match the target peripheral, which is great because some peripherals like the MicroSD do not function above certain speeds.
The case.. wow: the case is extremely impressive, small, has a nice heft to it, quality plastic, built-in mounting threads (metal, not plastic), and feels nicely balanced and pleasant to hold (ever pick up an iPhone after holding a cheaper smart phone? Yeah, like that).
Here's where the hardware side of things becomes mediocre. The screen is nice and bright, but only supports up to 320x240. Additionally the screen and microprocessor are connected using SPI instead of the faster parallel connection supported by the lcd driver. This requires more processor overhead when rendering, giving you less cycles for actual processing work.
The device only has 192KB of ram.. that's it. Let me repeat this.. only 192KB of ram..
As in just enough for a framebuffer and no other in-memory data; or enough for other data but limited performance by constantly writing direct to the lcd driver (via SPI).
*Summary*
Overall though it's a good device. For anyone just connecting Grove modules, wiring up LEDs and switches, or messing around; this device is excellent.
For potential power users, read the details and consider the limitations. Personally I still feel like this device is a win, and I'm considering getting another. But your experience will vary based on what you're able or willing to put into the device.
