The FireBeetle 2 ESP32-C5 is a high-performance, low-power IoT development board designed for advanced smart home and extensive IoT applications. Its core strength lies in the groundbreaking Espressif ESP32-C5 chip, offering dual-band (2.4 & 5 GHz) Wi-Fi 6 for unparalleled wireless performance, a comprehensive multi-protocol hub supporting BLE, Zigbee, and Thread, and an advanced power management system with integrated solar charging. Powered by a 240 MHz RISC-V processor with 384 KB SRAM and 4 MB Flash, it achieves an ultra-low deep-sleep current of just 21 μA. This makes it an ideal solution for demanding applications. Whether for building a low-latency robotics controller, a solar-powered outdoor sensor, or a powerful, custom multi-protocol device for a Home Assistant ecosystem, the ESP32-C5 provides the necessary performance and flexibility.

Superior Wireless Performance with Dual-Band Wi-Fi 6

The ESP32-C5 is Espressif's first chipset to integrate dual-band Wi-Fi 6, representing a monumental leap in wireless capabilities for IoT devices. By providing access to the 5 GHz band, the FireBeetle 2 ESP32-C5 bypasses the heavily congested 2.4 GHz spectrum, resulting in significantly higher transmission rates, lower latency, and dramatically reduced interference. This is critical for:

• High-Throughput Data Streaming: Ideal for developing custom IP cameras, FPV drones, or local servers. The high bandwidth of the 5GHz band ensures smooth and reliable streaming of high-definition video.
• Low-Latency Control: Facilitates the creation of highly responsive robotics, real-time interactive systems, and industrial controllers where precise command execution is essential.

Furthermore, Wi-Fi 6 technology enhances network efficiency through features like OFDMA (Orthogonal Frequency Division Multiple Access) for better multi-device performance and TWT (Target Wake Time) to reduce device power consumption, intelligently extending battery life.

Flexible Power, Endless Deployment

The FireBeetle 2 ESP32-C5 is engineered with a robust and versatile power management system, providing the flexibility to deploy projects anywhere, regardless of power constraints.

• Versatile Power Supply Options: The board supports multiple power inputs, including Type-C, 5V DC, and a PH2.0 lithium battery interface, complete with integrated charge and discharge management for seamless operation.
• Integrated Solar Charging: Featuring the same high-efficiency solar power management chip as the popular 5V@1A Solar Power Module (DFR1075), this board allows for a direct connection to a 4.5V~6V solar panel. This enables true off-grid, autonomous deployments for outdoor environmental sensors, remote monitoring stations, and other long-term projects.
• Intelligent Power Saving: Maximum battery life is achieved with an ultra-low deep-sleep current of 21 μA. The board also features a controllable 3.3V power output (VCC_EN), which can completely cut power to external sensors and peripherals, further minimizing energy consumption.

Unified Wireless Hub for Future-Proof IoT

Extending beyond a single protocol, the FireBeetle 2 ESP32-C5 is a true multi-protocol hub, supporting Wi-Fi, Bluetooth 5 (BLE), Thread 1.3, and Zigbee 3.0. This versatility enables the creation of sophisticated, cross-platform IoT ecosystems.

• Matter-Ready: The board is equipped to develop Matter Wi-Fi or Matter Thread end devices, ensuring seamless interoperability with major smart home platforms like Apple HomePod and Google Home.
• Advanced Gateway Functionality: This is especially powerful for Home Assistant enthusiasts, allowing the board to act as a reliable Wi-Fi MQTT client, a native Zigbee device, or a future-proof Thread/Matter node, centralizing all smart devices in the network.

Rapid Prototyping with the FireBeetle Ecosystem

Designed with the developer in mind, the FireBeetle 2 ESP32-C5 incorporates features that simplify development and accelerate prototyping.

• Onboard GDI for Displays: The integrated GDI (General Display Interface) allows for an easy, solder-free connection to a wide range of DFRobot screens, making it simple to add a graphical user interface or data dashboard to a project.
• Convenient Peripherals: Features a user-friendly PH2.0 battery interface for secure and convenient battery connection and is fully compatible with DFRobot's extensive ecosystem of Gravity and Fermion series sensors and modules.
• Multi-Platform Software Support: Projects can be programmed using C/C++ (Arduino IDE) or MicroPython, giving developers the flexibility to choose the development environment that best suits their skills and project requirements.
