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

This FireBeetle 2 ESP32-C5-U(N4) IO Expansion Kit combines the FireBeetle 2 ESP32-C5-U(N4) development board with a dedicated IO expansion board for faster IoT prototyping. The expansion board brings out the development board interfaces in clearly organized functional sections, allowing sensors and peripherals to be connected quickly without soldering. Based on the ESP32-C5-WROOM-1U-N4 module, this IoT development kit combines a 240 MHz RISC-V processor, dual-band Wi-Fi 6, Thread 1.3, Zigbee 3.0 and flexible power management for smart home, wireless sensing and industrial IoT projects.

Dedicated IO Expansion Board for Faster Solder-Free Prototyping

This ESP32-C5 development kit includes a dedicated IO expansion board with 11 IO connections, 3 I²C interfaces, UART, SPI, RST, VIN and VOUT connections. The organized interface layout reduces wiring work during prototyping and provides a convenient way to connect sensors, displays and other peripherals without repeatedly soldering headers or building an additional breakout circuit.

2.4 GHz + 5 GHz Dual-Band Wi-Fi 6

This ESP32-C5 development board supports 2.4 GHz and 5 GHz Wi-Fi with IEEE 802.11a/b/g/n/ac/ax compatibility. The additional 5 GHz band provides an option for higher-throughput, lower-latency communication with less interference than crowded 2.4 GHz environments. Wi-Fi 6 technologies including OFDMA and Target Wake Time help improve network efficiency while supporting lower-power connected applications.

U.FL External Antenna Connector for Enclosed IoT Installations

This FireBeetle development board features a U.FL (IPEX) external antenna connector supporting external 2.4 GHz / 5 GHz dual-band antennas. External antenna placement allows the antenna to be positioned outside metal enclosures, control cabinets or waterproof housings to minimize signal attenuation caused by shielding. The package includes a 2.4GHz communication FPC antenna.

Thread 1.3, Zigbee 3.0 and Matter-Oriented Connectivity

This wireless IoT development kit supports Wi-Fi, 2.4 GHz low-power wireless communication and IEEE 802.15.4, including Thread 1.3 and Zigbee 3.0. This protocol combination supports development of Matter Wi-Fi/Thread end devices for cross-platform smart home applications. When paired with an external MCU, the ESP32-C5 platform can also be used in Thread Border Router, Matter Gateway or Zigbee Bridge development scenarios.

Solar Charging and 21 μA Deep Sleep for Low-Power Deployment

This low-power IoT development kit supports USB Type-C input, 5 V DC input and 4.5–6 V solar panel input for Li-ion battery charging. The power management design uses the same solar power management IC as the DFRobot 5 V/1 A Solar Power Manager and supports battery level monitoring. A software-controllable 3.3 V output allows external sensors to be powered off when inactive, while the 21 μA Deep Sleep current under battery power helps reduce standby consumption in long-term monitoring projects.
