DFRobot FireBeetle is a low - power series of development hardware for the Internet of Things. The Firebeetle ESP8266 development board comes with IoT WiFi, TCP/IP, a 32 - bit MCU, a 10 - bit ADC, and multiple interfaces like HSPI, UART, PWM, I2C, and I2S. In DTIM10, it only consumes 1.2mW to maintain a WiFi connection. With 16MB of outer SPI flash memory, it's great for storing programs and firmware. It's Arduino - compatible, which lowers the programming barrier. You can directly use Arduino programming codes on the ESP8266, making operation easier and the board more stable. During programming, it supports RTOS SDK in Linux, Arduino IDE, and Micropython. Note that there are some bugs for developers to fix. Sometimes, peripherals may not work perfectly with Arduino sample codes. Many Arduino functions are still being developed. You can try RTOS and MicroPython for a better experience. Features include compatibility with the FireBeetle series, Arduino programming, a built - in 32 - bit Tensilica L106 MCU and 10 - bit ADC, support for multiple programming platforms, IEEE802.11 b/g/n WiFi, TCP/IP, lithium battery use, low power consumption, OTA updating, and STA/AP/STA + AP modes. Specifications cover an operating temperature range of - 40℃ to + 85℃, 3.3V operating voltage, 3.3 - 5V input voltage, and more details about memory, current, and interfaces. Documents include a product wiki and more materials.
Using the FireBeetle ESP8266 is quite straightforward. First, if you're familiar with Arduino programming, you can directly write and upload your codes to the board. It's really user - friendly for beginners because of this Arduino compatibility. When it comes to power, you can use a lithium battery (up to 500mA charge current) or connect it via USB. Just make sure the input voltage is between 3.3V and 5V. For programming, you can choose from Linux's RTOS SDK, Arduino IDE, or Micropython based on your preference. Remember, there are some bugs in the system. So, if you notice that some peripherals aren't working as expected when using Arduino sample codes, don't worry. You can try switching to RTOS or MicroPython. Also, be aware of the operating temperature range. Keep it between - 10℃ and + 55℃ for normal use. As for maintenance, since it's a low - power device, you don't need to do much. Just keep it clean and dry. Avoid exposing it to extreme conditions, and it should serve you well for a long time.
