DFRobot FireBeetle 2 ESP32-P4 is a compact board with MIPI DSI/DSI, microphone, WiFi 6, and GPIO headers

DFRobot FireBeetle 2 ESP32-P4 development board features an ESP32-C6 wireless module, two USB-C ports, GPIO headers, a microphone MIPI CSI and DSI connectors, and is offered with an optional carrier board enabling easy access to all I/Os as part of a development kit for the board.

Like many other ESP32-P4 boards, such as the ALIENTEK DNESP32P4M, the Waveshare ESP32-P4-Module-DEV-KIT, or the ESP32-P4-Function-EV-Board, the DFRobot board uses an ESP32-C6 for Wi-Fi and Bluetooth connectivity. Other features include support for USB 2.0 OTG, a digital microphone header, microSD card slot, programmable buzzer, ADC/DAC, and an onboard CH343 USB-to-serial chip for programming via USB-C. It comes with expansion headers for easy access to I/Os from both the ESP32-P4 and C6, making it suitable for compact AIoT and lightweight machine learning applications.

The FireBeetle 2 ESP32-P4 devboard can be programmed through the Arduino IDE. To get started, you just need to add the correct board URL in the Arduino settings, install the ESP32 board package, and select the FireBeetle 2 ESP32-C6 board. The board also supports ESP-IDF with RTOS, and it can run small machine learning models using TensorFlow Lite for Microcontrollers with ESP-DL or other tools. The USB OTG works with ESP-IDF’s USB Host and Device stack, supporting HID, MSC, and CDC, and SDKs for display and camera are available in ESP-IDF. The onboard ESP32-C6 module may support Matter and Thread for Smart Home use. DFRobot also gives docs, tutorials, and code examples on their Wiki.

The FireBeetle 2 ESP32-P4 development kit is available for purchase now on DFRobot’s store for $13.90, but the board itself is only shown as “coming soon” for $11.90. It looks like it may also be called the “FireBettle 2 ESP32-P4 AI Vision board”, but the company is not super clear about that. If times are tough or you’d rather not pay $13.90, there is also a contest going on where DFRobot will be giving away free FireBeetle 2 ESP32-P4 kits along with a compatible SEN0173 camera module. To participate, you need fill out the forum with your background and camera-based project idea before August 8, 2025.
