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 &Bluetooth dual-mode communication. 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.

You may also check Bluetooth microcontrollor selection guide for more information.

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, compatible with arduino UNO and reduce the entry barrier.

The small size and high performance makes FireBeetle become idea solution for IOT low power consumption projects.

Version Upgrade:

1. Add a new anti-reverse connection silk-screen.

2. Change the Lipo battery connecter direction.

Compatible with products in the DFRobot FireBeetle serials
