1. Product Description
1.1 Product Introduction
The FireBeetle 2 ESP32-P4 is a high-performance microcontroller (MCU) development board designed based on the ESP32-P4R32 chip. It has powerful processing capabilities in image processing, supporting up to 1080p@30fps video playback and 1080p@30fps image shooting. The development board integrates WiFi and Bluetooth functions, making it suitable for various HMI (Human-Machine Interface) application scenarios such as digital photo albums, home central control screens, intelligent security systems, and smart doorbells.
The development board comes with pre-soldered pin headers and is paired with a dedicated IO expansion board for FireBeetle 2 ESP32-P4. It allows easy connection to various peripherals without the need for a breadboard or additional soldering. The development board leads out multiple sets of I2C interfaces and power pins, solving the problem of insufficient pins when building projects. The back of the expansion board is marked with silk-screened pin function mappings, enabling users to easily understand the pin functions without referring to documents.
High-definition Large-screen Display
The FireBeetle 2 ESP32 P4 integrates an MIPI-DSI interface, which can be directly connected to the Raspberry Pi DSI series display screens. The built-in JPEG decoder of the ESP32-P4 is mainly used for efficiently parsing and decompressing JPEG format image data, while the pixel processing accelerator is specifically designed to improve the processing speed and quality of image data. Thanks to these hardware advantages, the development board significantly enhances the display performance of images and videos, supporting smooth playback at up to 720p@88fps or 1080p@30fps, bringing a good visual experience of human-machine interaction to the project. Using the FireBeetle 2 ESP32 P4, a series of related projects such as digital photo albums, home central control screens, and multimedia advertisement displays can be created.
High-definition Camera Capture
The FireBeetle 2 ESP32 P4 integrates an MIPI-CSI interface, which can be directly connected to the Raspberry Pi CSI series cameras. The built-in JPEG encoder of the ESP32-P4 is responsible for efficiently compressing the original image data into JPEG format. The image signal processor performs real-time optimization and enhancement on the captured images, and the H264 video encoder ensures the real-time encoding of high-quality video streams. These features work together to greatly improve the image capture performance of the camera, supporting high-definition shooting at up to 720p@88fps or 1080p@30fps, enabling smooth shooting and video recording functions. Using the FireBeetle 2 ESP32 P4, various image capture and processing projects such as intelligent security systems, smart doorbells, and remote video conference cameras can be created.
Rich Expansion Interfaces
The FireBeetle 2 ESP32-P4 development board, with a size of only 25.4x60mm, exposes a rich and easy-to-use set of peripheral interfaces, reducing the difficulty of connecting external devices. The development board integrates the ESP32-C6 module, endowing the development board with wireless communication functions. The development board exposes a Type-C USB OTG 2.0 high-speed interface, which theoretically has a maximum data transmission speed of up to 480Mbps, enabling high-speed communication between the development board and USB devices. It has an on-board MIC, which can be used for sound collection and voice recognition. It also has an on-board TF card slot, which provides a convenient large-capacity storage solution for the project, enabling easy local storage and reading operations of media files such as pictures and videos.

3. Tutorial - First Time Use
3.1 Arduino IDE Configuration
When you use the ESP32 for the first time, you need to know the following steps:
- Add the ESP32 development board in Arduino IDE (How to add the ESP32 board to Arduino IDE?)
- Select the development board and serial port
- Burn the program
3.2 Select Development Board
- Click Tools->Board, select "ESP32P4 Dev Module".
- The development board needs to be set before burning the code:
- USB CDC On Boot:
- Enabled: Print serial port data through the USB interface
- Disabled: Print serial port data through TX and RX
- Partition Scheme: Disk partitioning scheme. Please select the appropriate storage space according to the Flash of the development board.
- Port: Development board port (Just make sure the COM number is correct, which has nothing to do with the subsequent chip model.)
- USB CDC On Boot:
3.3 LED Blinking
- Copy the code into the window and click "Upload" to upload the code.
int led = 3;
void setup() {
pinMode(led,OUTPUT);
}
void loop() {
digitalWrite(led,HIGH);
delay(1000);
digitalWrite(led,LOW);
delay(1000);
}
- Wait for the burning to complete, and you can see the on-board LED light start to flash.
