FireBeetle ESP32 IOT Microcontroller with WiFi

The DFRobot FireBeetle series are power-saving microcontrollers, specifically designed for Internet of Things (IoT) projects. These series' microcontrollers target low-power IoT nodes, to build the IoT hardware platform quickly and easily.  The FireBeetle Board - ESP32 integrates a dual-core ESP-WROOM-32 module, which supports MCU and Wi-Fi & Bluetooth dual-mode communication. The electrical current in deep sleep mode is only 10μA. The ESP32 FireBeetle board supports two power supply methods: USB 5V and 3.7V via external LiPo / Lithium battery. The board also features a built-in charging regulator so you can recharge your LiPo battery via the USB port. The FireBeetle Board-ESP32 has a special hardware design for the Arduino IDE. This way, you can load programs onto the microcontroller without having to manually switch the boot mode. A pin mapping for the FireBeetle ESP32 is also available in the Arduino DIE. The small size and high performance make FireBeetle an ideal solution for low-power IoT projects. We recommend the ESP32 for advanced users only, as it is not yet supported by all Arduino libraries.

There are three types of FireBeetles: the board main control, the cover expansion cards, and the general accessories.
