FireBeetle ESP8266 IOT Microcontroller with WiFi

The DFRobot FireBeetle series are energy-saving microcontrollers, specifically designed for Internet of Things (IoT) projects. These series of microcontrollers aim at low-power IoT nodes, making it quick and easy to build the IoT hardware platform. FireBeetle Board - ESP8266 is equipped with IoT WiFi, TCP/IP, 32-bit MCU, 10-bit ADC, and numerous interfaces like HSPI, UART, PWM, I2C, and I2S. The electric current in deep sleep mode is only 46uA. The ESP8266 FireBeetle Board supports two power supply methods: USB 5V and 3.7V through external LiPo / Lithium Battery. The board also has a charging controller built in so you can charge the LiPo battery using the USB port. The small size and high performance make FireBeetle an ideal solution for low power consumption IoT projects. The ESP8266 is compatible with Arduino programming and can be easily programmed with Arduino.

There are three types of FireBeetle: The main control boards, the expansion covers and the general accessories.
