FireBeetle 2 ESP32-C5 IoT Development Board

The FireBeetle 2 ESP32-C5 is a low-power IoT board with dual-band Wi-Fi 6, BLE, Zigbee and Thread support, plus solar charging and ultra-low sleep current — ideal for smart home and advanced IoT projects.

The FireBeetle 2 ESP32-C5 is a low-power IoT development board built for smart home systems and more demanding IoT projects. It’s based on Espressif’s ESP32-C5 chip, which supports dual-band Wi-Fi 6 (2.4 GHz and 5 GHz) and brings together multiple wireless protocols, including BLE, Zigbee and Thread, on a single platform. At its core is a 240 MHz RISC-V processor with 384 KB SRAM and 4 MB Flash, offering plenty of performance while keeping power consumption low. In deep sleep, the board draws as little as 21 μA, making it well suited for battery-powered or energy-harvesting projects. The onboard power management system also supports solar charging, adding flexibility for outdoor or off-grid applications. This combination of wireless capability, processing power and efficient power management makes the FireBeetle 2 ESP32-C5 a strong choice for applications such as low-latency robotics control, solar-powered environmental sensors, or custom multiprotocol devices integrated into a Home Assistant setup.
