FireBeetle Board ESP32-E with soldered socket strips

The FireBeetle ESP32-E features a power-saving ESP-WROOM-32E microcontroller specifically designed for Internet of Things (IoT) projects. This FireBeetle series microcontroller targets low-power IoT nodes to quickly and easily build the IoT hardware platform. The electrical current in deep sleep mode is only 10μA. The ESP32-E FireBeetle board supports two power supply methods: USB 5V and 3.7V via external LiPo / lithium battery. The board also has a charging controller built in so you can charge the LiPo battery via the USB port. FireBeetle Board-ESP32 has a special hardware design and is compatible with the Arduino IDE. Thus, you can load programs onto the microcontroller without manually switching the boot mode. Pin mapping for the FireBeetle ESP32 is also available in the Arduino IDE. The small size and high performance make FireBeetle an ideal solution for low-power IOT projects. The board also includes a GDI (General Display Interface) for connecting DFRobot displays via a flat ribbon cable.

Info: This is the version with soldered socket strips, making it easy to plug in Dupont cables.
