FireBeetle 2 ESP32-E (N16R2) is a low-power IoT development board built around the ESP32-WROOM-32E-N16R2 module. It combines a dual-core Tensilica LX6 processor running at up to 240MHz with 16MB Flash and 2MB PSRAM, giving you more room for connected applications, user interfaces, and sensor-driven projects.
The board supports dual-mode WiFi and Bluetooth communication and includes an onboard GDI display interface for quick display integration. This makes it a practical choice for control panels, smart home nodes, data monitoring terminals, and other projects that benefit from both wireless connectivity and a local UI.
For portable and always-on designs, it features an onboard charging circuit and a PH2.0 lithium battery connector with dual power supply support and automatic switching. It also supports multiple development environments including Arduino IDE, ESP-IDF, and MicroPython, and is compatible with the FireBeetle V2 series ecosystem.
Ideal for home automation upgrades, wireless robot control, environmental data logging, smart lighting systems, and display-based control panel development with LVGL-style interfaces.
