About this item

The DFRobot FireBeetle ESP32 IoT Microcontroller is a powerful, compact, and energy-efficient development board designed specifically for IoT applications. Built around the ESP32 dual-core processor, it combines Wi-Fi and Bluetooth 4.2 (BLE and Classic) connectivity in a small form factor, making it ideal for wireless sensor networks, smart home devices, wearable electronics, and automation systems. The board supports ultra-low power operation, featuring multiple sleep modes that make it suitable for battery-powered projects. It includes onboard Li-ion battery charging and power management circuits, enabling direct battery connection and charging via a micro-USB port. With a rich set of interfaces—such as GPIO, I2C, SPI, UART, PWM, and ADC—the FireBeetle ESP32 provides extensive flexibility for integrating sensors, actuators, and displays. It also features a separate USB-to-Serial chip, making it easy to upload code and debug. Thanks to its compatibility with the Arduino IDE and ESP-IDF, this board is accessible for both beginners and advanced developers. Whether you’re building a connected weather station, remote monitoring device, or BLE-enabled wearable, the FireBeetle ESP32 delivers reliable performance, low power consumption, and wireless flexibility in one compact package.
