Waveshare ESP32-P4-ETH Development Board with 100Mbps RJ45 Ethernet

The board requires a stable 5V DC power supply connected via the dedicated DC jack or the 5V pin on the GPIO header. Ensure your power source can provide sufficient current for connected peripherals like cameras or displays, as the board itself has a low operating current typical of ESP32 chips. Using a high-quality 5V/2A adapter is recommended for development with all features active.

You can develop for the ESP32-P4-ETH using the official Espressif IoT Development Framework (ESP-IDF) which provides full access to hardware features. Support in the Arduino Core for ESP32 is expected as the ESP32-P4 ecosystem matures. PlatformIO is also a viable option. Begin by installing the latest ESP-IDF, selecting the ESP32-P4 target, and connecting via the USB port for serial communication and flashing.

Connect a compatible MIPI-CSI camera module to the dedicated FPC connector, ensuring the cable is seated correctly. For displays, use a MIPI-DSI compatible screen. You must then configure the ISP and display drivers within your ESP-IDF project. Example code for initializing the camera pipeline and setting display parameters is provided in the ESP-IDF examples. Remember to account for the higher power draw when both peripherals are active.

Yes, the Ethernet peripheral operates independently on the ESP32-P4. You can run a web server or MQTT client over Ethernet while using SPI, I2C, or UART to communicate with sensors. The board's dual-core architecture helps manage these concurrent tasks efficiently. Configure the Ethernet using the ESP-IDF's network stack (lwIP) and assign a static IP or use DHCP as required by your network.
