The FireBeetle 2 ESP32-C6 IoT is built around the powerful ESP32-C6 chip, it features a 160MHz RISC-V 32-bit processor and supports multiple communication protocols such as Wi-Fi 6, Bluetooth 5, Zigbee 3.0, and Thread 1.3, providing seamless integration into diverse IoT networks. The board offers various power supply options, including Type-C, 5V DC, and solar charging for lithium batteries, managed by a solar power manager for optimised energy use. This flexibility allows for well-run energy management and a range of deployment choices. The inclusion of Wi-Fi 6 provides lower latency and reduced power consumption, while solar charging capabilities allow for deployment in areas without power lines. Additionally, the board features battery level detection, providing real-time monitoring of the device's battery status.
