Wio Link FAQ
-
Power & Battery － Does Wio Link come with a Lipo battery?
Nope. Each Wio Link goes with a micro USB cable for charging or you can got a 3.7V Lipo battery locally. Here’s the specs for your kind reference - maximum input voltage: 4.2V; maximum charging current: 500mA -
Power & Battery - Can I use a power adapter with Wio Link? Which type? And common battery holders?
There are two ways to power the Wio Link, Micro USB cable or a 3.7V Lipo battery. If both Micro USB and battery are plugged into the board, the battery will be charged by the USB power. You can use all kinds of power adapter which got Micro USB cable and 5Vdc output. The battery holder is a JST-2.0 connector. -
Power Consumption - What’s the power consumption of Wio Link?
The average power consumption is 70mA. With a battery of 700mAh, it can keep alive up to 10 hours. There are Low-Power-APIs which allows you to change the Wio Link from working-mode to sleeping-mode. It will reduce average power consumption to 150uA or less. -
Grove Cables - Are the Groves equipped with cables in all kits?
Yes, we have each Grove modules packed with one standard 4-pin Grove cable. -
RESTful APIs - Where are the endpoints? The calls aren’t required to go through some cloud servers are they? Is it an internet connection required or can they be made all through a local network?
We deploy the REST API server to iot.seeed.cc, so you can get access to sensor and actuator from iot.seeed.cc. At the moment, Wio Link must connect to the Internet. Also, we will open-source the server so as to enable users deploy local servers in very simple Docker way. With local servers deployed, they can utilize the compiling and data exchange service locally instead of going online. -
Programming Methods Supported - Will other programming methods be supported, such as Arduino IDE?
Wio Link can be programed with Arduino IDE, in that case it will lose the functionality of RESTful APIs except you implement another one in the same time. Wio Link is mostly expected to archive the Web of Things conversion for physical hardwares, so interactions are expected to perform in web / internet. But no worries, the software architecture is flexible, you can pull down the source code to local and connect Wio Link to the local servers, then you could modify the source code which will be compiled.
If you would like to interact with Arduino or RPI, you can develop a 3rd-party module driver and here’s the guide: github.com/Seeed-Studio/Wio_Lin … ve_example -
Platform Supported -Does Wio Link support Windows Platform?
By now Wio Link provides Android and iOS two mobile Apps. We have all services as RESTful API, such like user accounts and OTA, following API documents, the third-party developers can build their own applications say Mobile Apps or Desktop Apps.
Wio Link is an community friendly project. It won’t be limited to a certain platform. We really expect people can play with Wio Link in their way. -
Can I use Wio Link to interact with existing systems?
Yes. Who Link can interact with your existing system in several ways. First, connect any GPIO of Wio Link to other system, select “Generic Digital Input” or “Generic Digital Output” virtual Grove modules in the mobile App, then send/read signals to/from the existing system with RESTful API calls. Second, connect the analog port of Wio Link to other system, select “Generic Analog Input” virtual Grove module in the mobile App, then read analog measurement for some physical quantity of your existing system. Third, to interact with existing system more flexible, you can develop a 3rd party module driver in which dispatch the requests from internet to your existing system through I2C or UART interface. We have a guide[1] about how to develop 3rd party module driver and also we can provide technical support for your development.

Is there any detailed documentation about Wio Link?
Yes. We have wiki pages for Wio Link. Please have a look at iot.seeed.cc. -
How many Groves supported on Wio Link?
There are 150+ kinds of plug and play Groves modules available, among which 36 were supported on Wio Link till now, and you can find most of them in the Rewards, we’re working to add more continuously.
