Description Wio Link is designed to simplify your IoT development. It is an ESP8266 based open-source Wi-Fi development board to create IoT applications by virtualizing plug-n-play modules to RESTful APIs with mobile APPs. The traditional methodology of building IoT applications consists of electronic engineering, micro-controller programming, network programming, IoT protocols handling and application development. Every step involves various hardware and software knowledge and challenges. This time, we define a new way to create IoT applications. No hardware programming. No breadboard. No jumper wires. No soldering. 3 steps. 5 minutes. Build your own IoT applications!
