Parallax WX ESP8266 WiFi Module SIP-10

The Parallax WX ESP8266 Wi-Fi module adds a new dimension of connectivity to your microcontroller applications. Special pre-loaded firmware makes it easy to configure the module to fit your project, simply connect to the module with your smartphone, tablet, or computer's web browser.

The Parallax WX ESP8266 Wi-Fi module can be its own wireless access point (AP), a station (STA) on another Wi-Fi network, or both at once briefly to join another network. In either mode, it can serve its own configuration pages as well as user-created web pages that make it possible for devices to interact with a microcontroller through the Wi-Fi module. It can also send and receive a variety TCP/IP messages for Internet of Things (IoT) projects, on Wi-Fi networks configured to allow it access. By serving its own firmware upgrade page, this module allows you to pick and upload the latest open source firmware revision, or even variations that support specific applications as they become available.

Bridge STEM and robotics efforts with computer science and web design programs. The Parallax WX ESP8266 Wi-Fi module brings a new IoT-capable dimension to an existing fleet of educational robots, and opens up opportunities to explore how HTML and Javascript can interact with embedded systems. These BASIC Stamp tutorials for the WX Wi-Fi module illustrate what can be done through any system with a host microcontroller supporting serial communication.
