DFRobot FireBeetle ESP32 IOT Microcontroller

DFRobot FireBeetle ESP32 IOT Microcontroller is a low-power consumption microcontroller designed for Internet of Things (IoT) projects. The FireBeetle Board integrates a Dual-Core ESP-WROOM-32 ESP32 WiFi-BT-BLE MCU Module for Wi-Fi and BLUETOOTH® dual-mode communication. The board has a 10μA electric current in deep-sleep mode and the main controller supports USB and 3.7V external lithium battery power supply methods. The USB and external DC can charge the LiPo battery directly.

The FireBeetle ESP32 Board supports Arduino, IDF ( Linux ), micropython and has a pin mapping for Arduino IDE. The board has a special hardware design for Arduino IDE to make a download without switching boot-mode manually. The board can be configured with Dx transport, compatible with UNO. The FireBeetle is small with high performance making it an ideal solution for IoT low power consumption projects.
