Description
The FireBeetle ESP32 is a compact, low-power IoT development board built around the ESP-WROOM-32 dual-core processor with onboard Wi-Fi and Bluetooth. It is an ideal platform for students, makers, and educators developing connected electronics and battery-powered automation projects.
Dual-core processing and wireless connectivity
Powered by a 240MHz Tensilica LX6 dual-core processor with 16MB Flash and 520KB SRAM, this board handles both high-speed connectivity and independent program tasks. It features dual-mode communication with 2.4GHz 802.11 b/g/n Wi-Fi and Bluetooth v4.2 BLE.
Over 250 detailed tutorials
The board comes with access to over 250 structured tutorials covering everything from basic software setup to advanced application development. These step-by-step guides provide practical assistance for beginners and seasoned developers.
Dual power supply with automatic switching
Power the board via standard USB or an external 3.7V lithium battery, supported by onboard charging and automatic power source switching. The board includes anti-reverse connection labelling to safeguard your battery setup.
Rich hardware interfaces and expansion
The board provides 10 digital I/O pins, 5 analog inputs, and dedicated buses for UART, SPI, I2C, I2S, and an SD card interface. This layout enables direct integration with a wide variety of external sensors and actuators.
Broad software and language support
Development is streamlined with one-click flashing and Arduino IDE pin mapping using Dx notation. It is fully compatible with Arduino IDE, ESP-IDF, MicroPython, and Mind+ graphical programming.
Compact footprint for IoT applications
Measuring 29 mm by 58 mm, this board is built for space-constrained installations and low-power remote nodes. It operates reliably in temperatures ranging from -40 degrees Celsius to 85 degrees Celsius.
