FireBeetle ESP32 IoT Microcontroller DFRobot

DFRobot FireBeetle series is the low-power consumption micro-controller intentionally designed for Internet of Things 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 10A 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.
