Product description: FireBeetle 2 ESP32-UE-N16R2 - IoT WiFi, Bluetooth - external antenna - DFRobot DFR1140
FireBeetle 2 ESP32-UE-N16R2 is an excellent choice for IoT application developers who value high performance and flexibility. Thanks to the ability to connect external antennas, the module significantly improves the range and quality of Bluetooth and WiFi wireless communication, making it ideal for applications in demanding environments. The microcontroller is equipped with a dual-core Tensilica LX6 processor clocked at up to 240 MHz. It supports WiFi communication in the 802.11 b / g / n standards and Bluetooth in the BLE version, which ensures fast data transfer. Large Flash memory (16 MB) and PSRAM (2 MB) allow for efficient data storage and the use of advanced libraries, such as LVGL, for designing graphical user interfaces. It supports a wide set of peripheral interfaces, such as 17 digital pins, 11 analog pins, 3 UART interfaces, SPI, I2C, I2S and 2 DAC interfaces. The possibility of powering via USB or an external 3.7 V lithium battery with automatic switching between power sources further increases the module's versatility.
The product is compatible with Arduino .
