FireBeetle 2 ESP32-E
Overview
The FireBeetle 2 ESP32-E is a high-performance development board based on the ESP-WROOM-32E module, featuring a dual-core Tensilica LX6 processor running at 240MHz. It integrates 4MB of flash and 520KB of RAM, providing robust WiFi and dual-mode Bluetooth (classic and BLE) connectivity for IoT applications. The board includes specialized features like a built-in battery charging circuit and a dedicated GDI display port to simplify portable device design.
Why Choose This Part
The board offers a wide input voltage range of 3.3V to 5.5V and 18 GPIOs, making it highly adaptable for various power sources and peripheral configurations. It combines high-speed processing with low-power sleep modes and hardware-level RTC support for efficient power management. The inclusion of a dedicated display interface and integrated battery management significantly reduces the external component count for mobile prototypes.
Applications
Key Specifications
Getting Started
The FireBeetle 2 is fully compatible with the Arduino IDE, ESP-IDF, and MicroPython, allowing developers to choose their preferred software environment. Users should install the ESP32 board manager in Arduino IDE and use the onboard USB-C port for both programming and battery charging. The pinout is designed to be breadboard-friendly with a 2.54mm pitch for rapid prototyping.
