FireBeetle ESP32 IOT Microcontroller
Description Compatible with products in the DFRobot FireBeetle serials Low-power consumption Quick Response(the top frequency is 400KHz) Small size, convenient to install The FireBeetle ESP32 IOT Microcontroller 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 supports MCU and Wi-Fi and 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 booth-mode manually.
