ESP-WROOM-02 Wi-Fi Shield

This is a shield with ESP-WROOM-02 Wi-Fi module. It allows Wi-Fi communication on a micro controller board such as Arduino Uno R3 etc.

This product communicates with Arduino by serial. Please use the slide switch to choose hardware serial or software serial.

5 V or 3.3 V can both be connected to the micro controller board by using jumper socket to choose the preferred I/O voltage.

It's handy when you want Wi-Fi communication by micro controller boards with pins headers compatible with Arduino Uno R3, for example FRDM-K64F.

The pin header is not included. Please purchase them separately and solder them depending on your usage.
