Overview

Nowadays, WiFi is seen everywhere in our daily life and Arduino microcontrollers are getting more and more popular.

The keyestudio ESP13 shield is particularly designed for Arduino microcontrollers to connect the WiFi.

It adopts industrial grade chip ESP8266. It is ESP-13 with metal shield, with strong anti-interference ability.

The pin is compatible with the main control board such as Arduino Uno and Mega2560. Meanwhile, it uses the voltage conversion chip when connecting the Arduino MCU, which compatibles with 3.3V and 5V.

The serial port of the shield is controlled by a dual-dial switch, so that it can be used alone as an Arduino MCU expansion board or as an ESP8266 shield.

It configures WiFi and serial parameters based on Web Server.

It can not only be used as an independent ESP8266 development board, downloading official AT command firmware, NodeMCU open source firmware and so on, but also can be used as a stand-alone Arduino UNO shield, with all leadout pins.
