The FireBeetle 2 ESP32-E IoT Microcontroller is a compact, energy-efficient development board built around the ESP-WROOM-32E module, offering dual-core processing and reliable Wi-Fi and Bluetooth 4.2 connectivity. It features 32Mbit flash and 512KB SRAM, making it well-suited for connected projects like smart home automation, wearables, or low-power IoT applications. The board is optimized for long battery life and includes an onboard charging circuit for lithium batteries via a PH2.0 interface. It supports Arduino and MicroPython programming and is compatible with various Gravity sensors thanks to its fool-proof layout and clear labeling.This board adds convenient extras like an onboard RGB LED, a GDI (General Display Interface) port for direct screen connections, and a USB-C connector for modern compatibility. Thanks to its compact 25.4×60 mm size and stamp hole design, it’s easy to integrate directly into custom PCBs. Perfect for rapid prototyping and long-term deployment, this version also fixes several known hardware bugs from earlier ESP32 chips, improving overall stability, boot reliability, and secure communication. https://elecena.pl/product/27744260/dfrobot-firebeetle-2-esp32-e-iot-microcontroller 2025-01-23 https://elecena.pl/product/27744260/dfrobot-firebeetle-2-esp32-e-iot-microcontroller 2025-04-21 https://elecena.pl/product/27744260/dfrobot-firebeetle-2-esp32-e-iot-microcontroller 2025-05-05 https://elecena.pl/product/27744260/dfrobot-firebeetle-2-esp32-e-iot-microcontroller 2025-09-28 https://elecena.pl/product/27744260/dfrobot-firebeetle-2-esp32-e-iot-microcontroller 2026-02-21 https://elecena.pl/product/27744260/dfrobot-firebeetle-2-esp32-e-iot-microcontroller 2026-03-05 https://elecena.pl/product/27744260/dfrobot-firebeetle-2-esp32-e-iot-microcontroller 2026-03-14 https://elecena.pl/product/27744260/dfrobot-firebeetle-2-esp32-e-iot-microcontroller 2026-03-19 https://elecena.pl/product/27744260/dfrobot-firebeetle-2-esp32-e-iot-microcontroller 2026-04-12
