Product User’s Manual – ESPWiFi Shield
1.0 INTRODUCTION
ESPWiFi Shield is an Arduino shield which integrates famous ESP8266 WiFi module and
provides low cost WiFi solution with any Arduino projects. It is compatible with Arduino
Uno,Arduino Duemilanove,Arduino Mega2560,Arduino Leonardo and possibly other pin
compatible main boards.
ESP8266 WiFi shield provides easy and stable UART interface for users to communicate
with onboard ESP8266 module using Arduino boards. The module is preloaded with AT
firmware and the user can use provided library to implement WiFi solution in their Arduino
projects. Advanced users can even customise and upload their own firmware on this ESP8266
module and use it as an additional microcontroller to create an even more powerful
application together with Arduino boards.
ESP8266 WiFi shield has stackable side headers which allows more Arduino-compatible
shields to be stacked on top of it. This shield provides digital pins options for software and
hardware UART or even PC-ESP communication. It also provides GPIO pin breakout and a
small prototyping area for the users to construct small circuits suitable to their application.
The shield also comes with microSD slot which serves as file storage for the users.
Features:
●Onboard ESP8266 module with preloaded AT firmware
●Jumper selectors for software or hardware UART and PC-ESP communication.
●TX and RX LED indicators for ESP8266 WiFi module.
●ESP8266 3V3 GPIO pin breakout (including 9 digital I/O pins and 1 analog input pin)
●Prototyping area
●1 MicroSD card slot.
●Arduino Reset and ESP8266 Module Reset button.
