DFRobot FireBeetle 2 ESP32-UE (N16R2) IoT Microcontroller (16MB Fl., 2MB PS., Supports Ext Antenna, Wi-Fi & Bluetooth)

FireBeetle 2 ESP32-UE (N16R2) is a powerful IoT microcontroller that supports external Bluetooth & WiFi antennas and features 16M Flash and 2M PSRAM. This product enhances memory capacity and operating space, enabling superior performance for applications such as the LVGL graphics library for interface design and interaction. The support for external antennas with higher gain enhances the communication range of Bluetooth or WiFi, setting it apart from the onboard antenna version of the ESP32 development board.

Based on Espressif’s ESP32-WROOM-32UE-N16R2 module, this product features a 32-bit dual-core processor with a clock frequency of up to 240MHz and supports MCU, WiFi, and Bluetooth dual-mode communication. It is highly suitable for a wide range of IoT scenarios.
