DFRobot has officially introduced the FireBeetle 2 ESP32-P4, a compact microcontroller board built for computer vision and multimedia projects. Priced at $11.90, it pairs the ESP32-P4 SoC with a companion co-processor for Wi-Fi 6 and Bluetooth connectivity, targeting applications such as cameras, smart home devices, and interactive interfaces.

The ESP32-P4 includes a 360 MHz dual-core RISC-V processor with single-precision FPU and AI instruction extensions, enabling lightweight machine learning models such as TensorFlow Lite to run directly on the device.

A secondary 40 MHz RISC-V low-power core supports background and standby functions. The board is paired with 32 MB PSRAM and 16 MB Flash, along with dedicated memory blocks for both high-performance and low-power tasks.

The FireBeetle 2 is advertised to be optimized for multimedia and AI workloads with native MIPI-CSI and MIPI-DSI interfaces, allowing direct connection to Raspberry Pi-compatible cameras and displays without additional adapters.

A built-in image signal processor, JPEG/H.264 encoders, and pixel accelerators enable video capture and playback at up to 1080p@30fps or 720p@88fps. An onboard PDM digital microphone adds support for voice-driven features and audio AI.
