The DFRobot FireBeetle ESP32 IoT Microcontroller is built around an Espressif Systems ESP32 microcontroller module with integrated Wi-Fi and dual-mode Bluetooth connectivity. The high-performance module offers dual CPU cores: one to handle high-speed connections and one for standalone application development. The microcontroller supports USB and 3.7-volt external lithium battery power methods. The battery can be charged directly by the USB and external DC, making it ideal for low-power IoT projects.

The ESP32 IoT Microcontroller is compatible with FireBeetle covers and accessories as well as DFRobot’s Gravity Series modules. The microcontroller is also pin-compatible with Arduino Uno and supports the Arduino integrated development environment (IDE), MicroPython programming languages and Espressif IoT Development Framework (IDF).
