The FireBeetle series is a family of low-power consumption microcontrollers intentionally designed for Internet of Things (IoT) projects. Characterized by their compact form factor and high integration, these boards are primarily based on the ESP32 and ESP8266 platforms, offering robust Wi-Fi and Bluetooth connectivity. The lineup has expanded to include advanced models like the ESP32-C6 for Matter smart home applications and the ESP32-P4 for edge AI processing. This Wiki provides comprehensive datasheets, pinout diagrams, and power consumption analysis to assist developers in building energy-efficient connected devices and battery-powered sensor nodes.
