Introduction

DFRobot FireBeetle series is the low-power consumption micro-controller intentionally designed for Internet of Things (IoT) projects. FireBeetle Board - ESP32 integrates a Dual-Core ESP-WROOM-32 module, which supports MCU and Wi-Fi &Bluetooth dual-mode communication. The electric current is just 10μA in the deep-sleep mode. The main controller supports two power supply methods: USB and 3.7V external lithium battery. And both USB and external DC can charge the Lipo battery directly.
FireBeetle Board-ESP32 has made a special hardware design for Arduino IDE. You can make a download without switching boot-mode manually. It supports Arduino, IDF (linux), micropython etc. Moreover, FireBeetle made a pin mapping for Arduino IDE. It can be configured with Dx transport, compatible with UNO and reduce the entry barrier.
The small size and high performance makes FireBeetle become idea solution for IOT low power consumption projects.
Please kindly note that developers are the most common users of FireBeetle Board-ESP32 and not all of the peripherals have examples for reference, and there are still some bugs being found and fixed. For Arduino IDE, all GPIO function, I2C/SPI communication has been working. But the other functions are still under development. We recommend this board for experienced engineer.

Tutorial

In this tutorial, we'll show you some basic operation with FireBeetle-ESP32 Microcontroller.

Requirements

 

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.

https://git.oschina.net/dfrobot/FireBeetle-ESP32/raw/master/package_esp32_index.json

  • File->Preferences

  • paste url here

  • Click OK
  • Open Tools->Board->Boards Manager, waiting automatic update. You'll find FireBeetle-ESP32
Search “FireBeetle-ESP32”, Click Install

 

 

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

Sample Code - Blink

The default LED for FireBeetle Board-ESP32 is D9, input following code:

 


// 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_BUILTIN, OUTPUT);
}

// the loop function runs over and over again forever
void loop() {
  digitalWrite(LED_BUILTIN, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(1000);                       // wait for a second
  digitalWrite(LED_BUILTIN, LOW);    // turn the LED off by making the voltage LOW
  delay(1000);                       // wait for a second
}
