ESP8266
Dev Board

Getting Started

1. Download Arduino IDE (https://www.arduino.cc/en/Main/Software)
2. Setup ESP8266 support for Arduino IDE:
• Start Arduino and open Preferences window.
• Enter https://arduino.esp8266.com/stable/package_esp8266com_index.json into the Additional Board Manager URLs field.
• Open Boards Manager from the Tools > Board menu and find esp8266 platform.
• Select the version you need from the drop-down box.
• Click the Install button.
• Don't forget to select your ESP8266 board from the Tools > Board menu after installation.
3. Select "Generic ESP8266 Module"
4. Pick the following from the Tools menu:
• Upload Speed: 115200
• CPU Frequency: 80MHz
• Crystal Frequency: 26MHz
• Flash Size: 16MB
• Flash Mode: DOUT
• Flash Frequency: 40MHz
• Port: (the serial port of your USB cable)
5. Paste the code below into a new sketch and upload to the board:

const int LED_RED = 5;

void setup() {
    pinMode(LED_RED, OUTPUT);     // setup red LED as output
}

void loop() {

    digitalWrite(LED_RED, LOW);   // turn the LED on
    delay(1000);                  // wait for a second

    digitalWrite(LED_RED, HIGH);  // turn the LED off
    delay(1000);                  // wait for a second

}

If all goes well the board will program and the red LED will start blinking.
