DFR1140

DFR1140 is a FireBeetle 2 ESP32-UE (N16R2) IoT board. The FireBeetle 2 ESP32-UE is an IoT microcontroller based on the ESP32-WROOM-32UE-N16R2 module, featuring a connector for an external Wi-Fi/Bluetooth antenna. It is equipped with a Tensilica LX6 dual-core processor (240MHz), 16MB Flash, and 2MB PSRAM. It supports dual-mode communication via 2.4GHz Wi-Fi (802.11 b/g/n) and Bluetooth 4.2 (BR/EDR/BLE). The board operates on a 5V DC (USB-C) or 3.7V Li-ion battery, with automatic power switching and charging. Peripherals include 17 digital pins, 11 analogue pins, 3x UART, 1x I2C, 1x SPI, and an onboard GDI for display connections. It is programmable with Arduino IDE, ESP-IDF, and MicroPython. 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, Wi-Fi, and Bluetooth dual-mode communication. It is highly suitable for a wide range of IoT scenarios and remote robot control.
