There are already plenty of board or modules based on Espressif ESP8266 WiFi SoC, but if you don’t like soldering, or would rather avoid breadboards and some cables for your or your kids’ projects, Wio Link may be interesting, as all you need to is to connect Grove modules required for your applications to get started, and Seeed Studio also took care of the low level software part and a drag-and-drop mobile app is provided, so software programming has been made easy too.

- 3.4 ~ 4.2V via external battery
- Output DC Current – 1000mA MAX
- Charge Current: 500mA MAX
- Dimensions – 55mm*48mm
- Weight – 26g
- Certifications – CE/FCC/IC
That’s for the main board, and you can connect one or more of the many Grove modules available so far. Now just power the board with a USB charger or a LiPo battery, and start the mobile app, available for Android and iOS, in order to setup the board, by dragging and dropping the Grove module(s) you’ve connected. The app will also let you upgrade the firmware over the air (OTA).
Some sample applications include connected traffic lights, pet feeder, plant watering, and whatever you may think of, as you can see in the video below.
Seeed Studio has already raised well over their $20,000 target on the Kickstarter campaign in less than day, and while all $9 early bird rewards are gone, you could still pledge for a Wio Link development board for $12. You may also consider a kit with the board and some Grove modules starting at $29, and up to $89 for a kit with two Wio Link boards, and 16 Grove modules including sensors, a relay, some buttons, a servo, a speaker, and LED strip, and more. Shipping is $5 for most rewards, and free for the larger ones. Delivery is planned for March 2016.
