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

The FireBeetle 2 ESP32-UE (N16R2) is an exceptional IoT microcontroller that empowers innovative projects with its enhanced memory and operating capabilities. Imagine crafting an interactive interface using the LVGL graphics library; this microcontroller makes it effortless, thanks to its 16M Flash and 2M PSRAM, which offer robust support for sophisticated applications. Where it truly outshines others is in its ability to support external antennas for Bluetooth and WiFi, vastly improving communication range and reliability compared to an onboard antenna model.

This dynamic product incorporates Espressif’s powerful ESP32-WROOM-32UE-N16R2 module, featuring a dual-core processor capable of clocking up to 240MHz. It's engineered for diverse IoT scenarios, enabling seamless dual-mode communication across WiFi and Bluetooth. Picture streaming data from remote sensors efficiently or controlling smart appliances from afar; this microcontroller is at the heart of it all.

The FireBeetle 2 ESP32-UE is teeming with rich peripheral interfaces, providing 17 digital pins, 11 analog pins, and multiple interfaces including UART, SPI, I2C, I2S, and DAC. Such wide-ranging connectivity ensures you can link up with almost any additional hardware component or sensor you envision using in your project, pushing the boundaries of what's possible.

Adaptability extends to its power supply options, too. It effortlessly switches between USB and a 3.7V lithium battery in dual power mode, granting continuous performance. Plus, with support for both USB and external DC charging, power management becomes a breeze.

Coding and development flexibility are cornerstones of this microcontroller, supporting multiple programming environments like Arduino IDE, ESP-IDF, and MicroPython. Whether you’re just starting or possess seasoned expertise, it accommodates your learning and development style.

The thoughtful, compact design — measuring just 25.4mm × 60mm and featuring a stamp hole design — ensures easy embedding into PCB prototypes. This makes it an ideal choice for projects where space is at a premium or where seamless integration is required.

On the antenna front, the ESP32-WROOM-32UE enables the use of external antennas, a key differentiator from the onboard antenna of the ESP32-WROOM-32E, providing options for higher gain and increased range capability. By simply connecting an external omnidirectional or directional antenna, you can unlock new levels of connectivity, whether you're designing a remote-controlled car that needs to stay in contact over long distances or setting up a local network across multiple rooms.

Being part of the FireBeetle series, this microcontroller is among the low-power champions, perfect for energy-efficient applications. Its versatility and performance make it a valuable asset within any developer's toolkit. If this particular version doesn't entirely fit your needs, the FireBeetle Series Selection Guide provides a road map to other models, ensuring you find the perfect match for your ambitions. The FireBeetle 2 ESP32-UE (N16R2) truly stands as a beacon of innovation and connectivity in the expansive world of IoT.
