FireBeetle Board-ESP32 V3.0

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.

We have made a special hardware design for FireBeetle Board-ESP32 to make it compatible with 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. So its GPIO ports can be configured just through Dx transport. The board is also compatible with UNO, which greatly reduced the entry barrier.

The small size and high performance makes FireBeetle become ideal 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 to experienced engineers.

Board Overview

FireBeetle Board - ESP32 is not only compatible with ESP32 Pinout, but also compatible with Arduino IDE PinMap. Users can directly use Dx(x=0,1,2,3...9) to control the corresponding GPIO port when programming on Arduino IDE.

Tutorial

FireBeetle-ESP32 adopts CH340 serial chip that can be used without driver among most devices. If you find the driver is not installed automatically after plugging into the device, you can install it manually: click to download the CH340 driver program.

warning_yellow.png NOTE: when the main board have been installed under the Linux or MAC environment, you need to install the pyserial module onto the terminal. (Install it by using command sudo easy_install pyserial)

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
}
