As a society that has become extremely networked through all kinds of different communications methods and protocols, it’s not surprising that, over time, various Communications technologies would become more accessible to hobbyists and Makers, as well as more affordable as the tech’ advances. However, up until recently, building custom or ad hoc networks has always been quite a tricky task, and this is why the world has welcomed Espressif’s incredible range of communications modules with open arms, as these have made it not only easy to create custom and personalised wireless networks, but also relatively cheap to deploy once you’ve got a good plan in mind.

Thee FireBeetle ESP8266 IoT Microcontrollers are excellent examples of just how far Communications technologies have come, as they take all of the complexities of networking, and simplifies these to be far easier to understand, and simple to deploy, troubleshoot and maintain compared to methods of the past. These boards utilise the advanced ESP8266 Module for WiFi capabilities, and complement these with a built-in Tensilica L106 MCU and 10-bit ADC, so as to offer far more functionality than most other Development Boards within this price range, and these features and low price are what makes these boards the ideal choices for almost any low-power wireless projects – as well as so much more.

Please Note: This board is not designed to be beginner-friendly, and is targeted more towards experienced Makers who want more capabilities than what Arduino Boards typically offer. As such, the FireBeetle ESP8266 MCU may require some extra learning to get working just right, but this is a small price to pay for the amazing features that these boards offer.

Typical Applications for the FireBeetle ESP8266 IoT Microcontroller:

With so much power and a host of awesome features that really add to the functionality and value of the FireBeetle ESP8266 IoT Microcontroller, it just makes sense that this board is far more capable than many of the alternative choices within the same price range. With this in mind, we particularly like using these boards for projects such as:

  • Deploying rapid, ad hoc networks within homes, office spaces or even universities, connecting sensors and various other modules together for easy maintenance, monitoring and upkeep.
  • Turning your old-school manual light switches into automated or remote-controlled switches, possibly even using unique gestures or sounds to activate or deactivate lights, or even set the mood for fun, romance or extra productivity.
  • Building your own remote-access system that operates via SMS or Webhooks Callbacks, with time-limited entry-codes or and a higher level of overall control.

Of course, although these FireBeetle ESP8266 Boards do offer onboard WiFi capabilities, it’s important to remember that these boards would still be incredible even without that factor. So don’t be scared to use these boards for almost any applications that you would typically use Arduino Boards for, and you can choose to use or lose the WiFi capabilities as you see fit.


Additional Resources:

  • With so many features and nuances, the ESP8266 FireBeetle is a seriously advanced board, and as such, we recommend taking some time to learn more about these intricacies by reading through the official DFRobot ESP8266 FireBeetle Wiki Page.
  • Just in case you didn’t spot the tutorial featured in the table above, this ESP8266 Arduino IDE Tutorial is a great place to start if you are accustomed to using the Arduino IDE. Alternatively, if you’re accustomed to using other programming tools, or if you’re having troubles with the Arduino IDE for your project, you may also be interested in checking out this ESP8266 MicroPython Tutorial, or this ESP8266 FreeRTOS Tutorial for alternative options.
