DFRobot DFR1284 FireBeetle 2 ESP32-C5-U (N4) Dev Kit
DFRobot DFR1284 FireBeetle 2 ESP32-C5-U (N4) Development Kit combines a FireBeetle 2 ESP32-C5-U development board with a dedicated I/O expansion board for fast, solder-free Internet of Things (IoT) prototyping. The kit is based on the ESP32-C5-WROOM-1U-N4 module and features a 240MHz RISC-V processor, 4MB of Flash memory, and support for C/C++ and MicroPython development. Designed for connected applications, the DFR1284 supports dual-band 2.4GHz and 5GHz Wi-Fi® 6, Thread 1.3, Zigbee® 3.0, and IEEE 802.15.4 wireless connectivity. A U.FL external antenna connector improves signal performance in enclosed installations, while the expansion board provides organized interfaces for sensors, displays, and peripherals.
The development kit also features flexible power management with USB Type-C®, Li-ion battery, and solar charging support. Battery monitoring, software-controlled 3.3V power output, and a low deep-sleep current of 21µA help reduce energy consumption in long-term wireless deployments. These capabilities make the DFRobot DFR1284 ideal for smart home devices, Matter-enabled products, environmental monitoring, wireless IoT nodes, and industrial sensing applications.
