ΠΕΡΙΓΡΑΦΗ

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.

Rich peripheral interfaces

Including 17 digital pins, 11 analog pins, 3 UART interfaces, 1 SPI interface, 1 I2C interface, 1 I2S interface, and 2 DAC interfaces, it can meet various hardware connection requirements.

Dual power supply modes

Supporting USB and external 3.7V lithium battery power supply, it can automatically switch between power sources in dual power supply mode. It also supports USB and external DC charging modes.

Support for multiple programming methods

Including Arduino IDE, ESP-IDF, MicroPython, etc., catering to the programming preferences of different developers.

The difference between ESP32-WROOM-32E and ESP32-WROOM-32UE

The ESP32-WROOM-32E uses an onboard PCB antenna. This type of antenna is realized through PCB technology, does not require separate antenna assembly, is not easily damaged by touch, and is convenient for whole machine assembly. Onboard antennas can save space, reduce costs, and because they can be carefully positioned on the board, they can provide signal integrity. However, their gain may be lower than that of external antennas.

The ESP32-WROOM-32UE (this product), on the other hand, connects to an external antenna via a connector. External antennas can be installed on the outside of the device and include both omnidirectional and directional antenna types. The main advantage of external antennas is that they can provide higher gain, thereby enhancing the communication range of Bluetooth or WiFi.
