Product Overview
DFR1139 is a FireBeetle 2 ESP32-E (N16R2) IoT board (Dual-Core 240MHz, Wi-Fi/Bluetooth, LVGL Support). This board is based on the ESP32-WROOM-32E-N16R2 module. It features a 240MHz dual-core processor, 16MB Flash, and 2MB PSRAM. The board supports 2.4GHz Wi-Fi (802.11 b/g/n) and Bluetooth 4.2 BR/EDR & BLE. It operates on 5V DC via USB-C or a 3.7V Li-ion battery, featuring automatic power switching and charging. Peripherals include 17 digital pins, 11 analogue pins, 3x UART, 1x SPI, 1x I2C, and an onboard GDI for display connections. It is programmable with Arduino IDE, ESP-IDF, and MicroPython. The module measures 25.4mm x 60mm and utilizes an onboard PCB antenna for robust connectivity. Suitable for home automation renovation, remote control of robots, environmental data monitoring, smart lighting control and control panel UI design applications.
