    DFRobot FireBeetle is a series of low-power-consumption development hardware designed for Internet of Things (IoT). Fire beetle ESP8266 is a development board integrated with IoT WiFi, TCP/IP, 32-bit MCU, 10-bit ADC and multiple interfaces such as HSPI, UART, PWM, I2C and I2S. In DTIM10, the full power consumption to maintain a WiFi connection reached to 1.2mW. Equipped with 16MB outer SPI flash memory, ESP8266 is available for programs and firmware storage. Compatible with Arduino programming enables Firebeetle ESP8266 to lower the barrier of programming. The operator can implement Arduino programming codes directly onto ESP8266 to reduce the difficulty of operating and increase the stability of the board.

    warning_yellow.png NOTE: There still remains some bugs to be detected and fixed by developers. In some cases some peripherals may not work perfectly by embedding Arduino sample codes in ESP8266. Much more functions implemented in Arduino are still under development and improvement. An alternative way is to change development tool such as RTOS and MicroPython towards a more operating-friendly experience in some conditions.

      • FireBeetle ESP8266 IOT Microcontroller x 1
      • Micro USB Cable x1

    warning_yellow.png NOTE: CH340 driver is free to install for most of Windows OS, if you find there is no COM Port in Device Manager, please download the driver and install it.

    CH340 Driver

    Setup Arduino IDE Development Environment

    • Plug FireBeetle to your computer, install the driver manually.
    • Add FireBeetle Board URL to Arduino IDE
    • Open Arduino IDE, File->Preferences, find Additional Boards Manager URLs, copy the below link, and paste in the blank.

    For overseas users: https://raw.githubusercontent.com/DFRobot/FireBeetle-ESP8266/master/package_firebeetle8266_index.json


    paste url here

    • Click OK
    • Open Tools->Board->Boards Manager, waiting automatic update. You'll find FireBeetle-ESP8266

    Search “FireBeetle-ESP8266”, Click Install

    Now, the development environment has been installed, you can use it like a normal Arduino board.


    The default LED for FireBeetle Board-ESP8266 is D5 (IO2), input following code:

    // GPIO 2 (D5) has a LED_BLINK attached to it. Give it a name:
    int LED_BLINK = 2;
    // the setup function runs once when you press reset or power the board
    void setup() {
      // initialize digital pin LED_BUILTIN as an output.
      pinMode(LED_BLINK, OUTPUT);
    // the loop function runs over and over again forever
    void loop() {
      digitalWrite(LED_BLINK, HIGH);   // turn the LED on (HIGH is the voltage level)
      delay(1000);                       // wait for a second
      digitalWrite(LED_BLINK, LOW);    // turn the LED off by making the voltage LOW
      delay(1000);                       // wait for a second

    warning_yellow.png NOTE: ESP8266 has different pinmap in different development environment, For example: the LED connects IO2, which maps D5 in Arduino IDE It is totally different mean with 2 and D2 !

    Sample Code - Scan WiFi

    After you have installed the FireBeetle ESP8266 development environment, it will comes with a lot of sample code in Arduino IDE, you can find them in File > Examples. The follow sample code scans the around WiFi:

     *  This sketch demonstrates how to scan WiFi networks.
     *  The API is almost the same as with the WiFi Shield library,
     *  the most obvious difference being the different file you need to include:
    #include "ESP8266WiFi.h"
    void setup() {
      // Set WiFi to station mode and disconnect from an AP if it was previously connected
      Serial.println("Setup done");
    void loop() {
      Serial.println("scan start");
      // WiFi.scanNetworks will return the number of networks found
      int n = WiFi.scanNetworks();
      Serial.println("scan done");
      if (n == 0)
        Serial.println("no networks found");
        Serial.println(" networks found");
        for (int i = 0; i < n; ++i)
          // Print SSID and RSSI for each network found
          Serial.print(i + 1);
          Serial.print(": ");
          Serial.print(" (");
          Serial.println((WiFi.encryptionType(i) == ENC_TYPE_NONE)?" ":"*");
