DFR1222

DFR1222 is a FireBeetle 2 ESP32-C5 IoT development board (2.4 / 5GHz Wi-Fi 6, solar charging, home assistant). This 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 240MHz RISC-V processor with 384KB SRAM and 4MB flash, it achieves an ultra-low deep-sleep current of just 21μA. 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.
