Description :

– The DFRobot FireBeetle series is a low-power consumption microcontroller designed for Internet of Things (IoT) projects.
– The 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 board supports two power supply methods: USB and 3.7V external lithium battery. And both USB and external DC can charge the Lipo battery directly.
– The board is designed for use with the Arduino IDE and supports other development environments such as IDF (linux) and micropython.
– The small size and high performance make it an ideal solution for IoT low power consumption projects.
– It is recommended for experienced engineers as not all peripherals have examples for reference and there are still some bugs being found and fixed.
– Version upgrade includes new anti-reverse connection silk-screen and change in Lipo battery connector direction.
