INTRODUCTION
DFRobot FireBeetle series is a low-power consumption microcontroller 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 &Bluetooth dual-mode communication. The main controller supports two power supply methods: USB and 3.7V external lithium battery. Both USB and external DC can charge the Lipo battery directly.
Firebeetle esp32 has made a special hardware design for Arduino IDE. You can 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, is compatible with Arduino UNO and reduce the entry barrier.
The small size and high performance make FireBeetle become ideal solution for IOT low power consumption projects.
