The PHPoC P4S-347 Shield 2 is an advanced wifi shield for Arduino which connects Arduino Uno and Mega microcontrollers to the Internet. With its powerful libraries and built-in web application, the PHPoC Shield brings the great features of PHPoC to Arduino providing the bridge between the Arduino controller and the internet allowing you to create Arduino-powered IoT devices easily and quickly.

PHPoC Shield 2 communicates with Arduino through an SPI interface and connects to the Internet through WiFi. It supports various network and security protocols, adding plenty of capabilities to Arduino Uno and Mega. PHPoC Shield 2 is equipped with an embedded Web server, WebSocket server and a PHPoC interpreter, enabling users to create dynamic embedded web apps to real-time control and monitor sensors/devices.

Some web apps are built and preloaded into PHPoC Shield to help the users interact with Arduino easily via Web. Just by using the Web browser on your smartphone, tablet or PC, you can real-time control/monitor Arduino-connected things or change your network setting.

A variety of expansion boards that dock onto the PHPoC Shield are designed to add more advanced capabilities such as relays, DC motor controllers, stepper motor controllers and RS232/RS485 communications.

PHPoC Arduino Shield with Smart Expansion Board StackThe PHPoC WiFi Shield 2, along with the Smart Expansion Boards for PHPoC shield, makes a great combination, which provides users many powerful functions to easily interact with other devices, sensors and actuators.If you need a similar product but for wired LAN connectivity, see the P4S-348 PHPoC Shield 2 for Arduino.
