The DF Robot FireBeetle ESP32 is a low-power consumption microcontroller intentionally designed for IOT projects. The microcontroller integrates a Dual-Core ESP-WROOM-32 module, which supports MCU and Wi-Fi &Bluetooth dual-mode communication. The electric current is just 10μA when in deep-sleep mode. The main controller supports two power supply methods: USB and 3.7V external lithium battery. And both USB and external DC can charge the Lipo battery directly. A special hardware design for Arduino IDE has been made for the firebeetle esp32. You can also make a download without switching boot-mode manually. It supports Arduino, IDF (linux), micropython etc. Moreover, FireBeetle made a pin mapping for Arduino IDE. It can be configured with Dx transport, compatible with arduino UNO and reduce the entry barrier. Benefits Low-power consumption Quick Response (the top frequency is 400KHz) Cost-effective Small size, convenient to install
