FireBeetle ESP32 IOT Microcontroller (Supports Wi-Fi & Bluetooth

( DFR )
SG$28.70


INTRODUCTION

 

DFRobot FireBeetle series is the low-power consumption micro-controller specifically 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 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 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.

Please kindly note that developers are the most common users of FireBeetle Board-ESP32 and not all of the peripherals have examples for reference, and there are still some bugs being found and fixed. For Arduino IDE, all GPIO function, I2C/SPI communication has been working. But the other functions are still under development. We recommend this board for experienced engineer.
Version Upgrade: 1. Add a new anti-reverse connection silk-screen.  2.Change the Lipo battery connecter direction.
