The DFRobot FireBeetle is a series of low-power-consumption development hardware designed for the Internet of Things (IoT).

The Firebeetle 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 1.2mW.

Equipped with 16MB outer SPI flash memory, ESP8266 is available for programs and firmware storage. Being compatible with Arduino programming enables the Firebeetle ESP8266 to lower the ability barrier of programming. The operator can implement Arduino programming codes directly onto the ESP8266.

In the programming stage, the Firebeetle Board-ESP8266 supports RTOS SDK in Linux, Arduino IDE and Micropython. Please note this board comes with the headers pictured (which require soldering).

When using the Arduino IDE, some peripherals may not work perfectly by embedding Arduino sample codes with the ESP8266. Many more functions implemented in Arduino are still under development and improvement.

An alternative way is to change development tools such as RTOS and MicroPython towards a more operating-friendly experience in some conditions.
