FireBeetle ESP8266 IOT Microcontroller SKU: DFR0489
Introduction
DFRobot FireBeetle is a series of low-power-consumption development hardware designed for
Internet of Things (IoT). 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 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. Operator can implement Arduino programming codes directly onto ESP8266 to
reduce the difficulty of operating and increase the stability of board.
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.
