FireBeetle Board ESP32-E

The FireBeetle ESP32-E has a power-saving ESP-WROOM-32E microcontroller that was specifically designed for Internet of Things (IoT) projects. This FireBeetle series microcontroller aims at low power IoT nodes, making it quick and easy to build the IoT hardware platform. The electric current in deep-sleep mode only amounts to 10μA. The ESP32-E FireBeetle board supports two power supply methods: USB 5V and 3.7V via some external LiPo/Lithium battery. The board also includes a built-in charging regulator for recharging the LiPo battery via USB. The FireBeetle Board-ESP32 has a unique hardware design and is compatible with the Arduino IDE. This allows you to upload programs to the microcontroller without manually switching the boot mode. Pin mapping for the FireBeetle ESP32 is also available in the Arduino IDE. Its small size and high performance make FireBeetle an ideal solution for low power IoT projects. The board also includes a General Display Interface (GDI) which lets you connect the DFRobot display using a ribbon cable.
