DFRobot DFR1287 FireBeetle 2 ESP32-C5-U (N4) IoT Dev Board
DFRobot DFR1287 FireBeetle 2 ESP32-C5-U (N4) Internet of Things (IoT) Development Board is a compact, low-power platform built around the ESP32-C5-WROOM-1U-N4 module. DFR1287 features a 240MHz single-core RISC-V processor, 4MB Flash memory, and dual-band 2.4GHz/5GHz Wi‑Fi® 6 connectivity for reliable wireless applications. The board supports Thread 1.3, Zigbee® 3.0, and IEEE 802.15.4 communication, making the device well-suited for Matter-compatible smart home devices. A U.FL external antenna connector enables flexible antenna placement, improving wireless performance in enclosed installations.
Designed for battery-powered and remote IoT deployments, the DFRobot DFR1287 supports USB Type‑C®, DC, and solar power inputs. Integrated Li-ion battery charging, battery voltage monitoring, and a 21μA deep-sleep mode help maximize operating life. The development board provides 18 digital I/O pins, SPI, UART, I2C, I2S, ADC, PWM, and infrared transceiver interfaces. Support for C/C++ and MicroPython simplifies the development of wireless sensor nodes, environmental monitors, smart home controllers, and industrial IoT devices.
