INTRODUCTION DFRobot FireBeetle series is the low-power consumption micro-controller intentionally designed for Internet of Things (IoT) projects. FireBeetle Board - ESP32 integrates a Dual-Core ESP-WROOM-32 module, which supports MCU and Wi-Fi &Blth dual-mode communication. The electric current is just 10μA in the 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. FireBeetle Board-ESP32 has made a special hardware design for Ard IDE. You can make a download without switching boot-mode manually. It supports Ard, IDF (linux), micropython etc. Moreover, FireBeetle made a pin mapping for Ard IDE. It can be configured with Dx transport, compatible with ard and reduce the entry barrier. The small size and high performance makes FireBeetle become idea solution for IOT low power consumption projects.
