FireBeetle 2 FireBeetle 2 ESP32-C5-U (N4) Development Kit (Dual-Band Wi-Fi 6)

The FireBeetle 2 ESP32-C5-U (N4) Development Kit combines an ESP32-C5-WROOM-1U-N4 board with a dedicated breakout shield for solder-free prototyping. Powered by a 240 MHz RISC-V microcontroller with dual-band Wi-Fi 6, Thread 1.3, and Zigbee 3.0, it is well suited to hobbyists, educators, and engineers building low-power wireless sensor networks and Matter-compatible smart home devices.

Solder-free IO expansion board

The included expansion board breaks out 11 IO lines, 3 I2C interfaces, UART, SPI, RST, VIN, and switchable VOUT connections in clearly defined sections. This organised layout simplifies prototyping by letting you connect sensors and modules directly without soldering extra header circuits.

Dual-band Wi-Fi 6 connectivity

Operating across both 2.4 GHz and 5 GHz frequency bands, the board supports IEEE 802.11a/b/g/n/ac/ax wireless communication. The 5 GHz band bypasses congested 2.4 GHz environments for lower latency, while Wi-Fi 6 features such as OFDMA and Target Wake Time improve data efficiency and energy usage.

Thread 1.3 and Zigbee 3.0 support

Integrated IEEE 802.15.4 hardware supports Zigbee 3.0, Thread 1.3, and 2.4 GHz low-power communication. This multi-protocol capability allows developers to create Matter end devices or interface with host processors to create Zigbee bridges and Thread Border Routers.

External U.FL antenna connection

A standard U.FL (IPEX) connector lets you route external 2.4 GHz and 5 GHz dual-band antennas outside metal cabinets or weatherproof project enclosures. An adhesive 2.4 GHz FPC antenna is supplied in the box.

Solar management and ultra-low deep sleep

The board accepts 5 V DC via USB-C or 4.5 V to 6 V from a solar panel to charge an attached lithium-ion battery via the PH2.0 socket. A software-switchable 3.3 V output cuts power to external sensors when inactive, enabling a low standby draw of 21 μA in battery deep sleep mode.

Onboard GDI port and software ecosystem

A dedicated GDI connector simplifies connecting compatible display panels without extensive wiring. The platform can be programmed using standard C/C++ or MicroPython toolchains for environmental monitoring, agriculture, and home automation systems.
