FireBeetle 2 ESP32-C5 IoT Development Board

The FireBeetle 2 ESP32-C5 is a powerful, low-power IoT development board for smart home and IoT applications. The ESP32-C5 is Espressif's first chip with dual-band Wi-Fi 6 on 2.4 GHz and 5 GHz, enabling higher data rates, lower latency, and significantly less interference. In addition to Wi-Fi, the board also supports Bluetooth 5, Thread 1.3, and Zigbee 3.0 for versatile smart home integrations. The advanced energy management allows power supply via USB-C, 5 V DC, or directly via a 4.5–6 V solar panel with integrated charging management.

Features:

• Dual-band Wi-Fi 6 on 2.4 GHz and 5 GHz for fast, interference-free connections
• Multi-protocol hub with Bluetooth 5, Thread 1.3, and Zigbee 3.0 support
• Integrated solar charging management for self-sufficient outdoor applications
• Ultra-low deep sleep power consumption of only 21 μA for long-term operation
• GDI interface for solder-less connection of DFRobot displays
• Matter-compatible for cross-platform smart home integration

Application Examples:

• Solar-powered balcony plant sensors with long-term data logging
• Air quality monitoring with stable 5 GHz data transmission
• Custom Home Assistant sensor nodes via MQTT or Zigbee
• FPV drones and robots with low-latency video streaming
• Matter-enabled smart home devices for Apple Home, Google Home, and Alexa
