Waveshare ESP32-P4-ETH development board supports Ethernet and PoE

Waveshare ESP32-P4-ETH is a compact ESP32-P4 development board with Ethernet and PoE support, which looks very similar to the Olimex ESP32-P4-DevKit minus the pUEXT connector. However, we’ve also covered other ESP32-P4 boards with Ethernet (and other features) such as the ESP32-P4-Module-DEV-KIT, the ESP32-P4-NANO board, and the GUITION JC-ESP32P4-M3-DEV.

Design wise, the board also looks very similar to the Wiznet boards based on Raspberry Pi RP2xxx microcontroller such as the W55RP20-EVB-Pico, the W6300-EVB-Pico2, and the W5100S-EVB-Pico2 boards, but you can also run multimedia workloads with MIPI camera and display interfaces, hardware video encoding, audio processing, AI speech functions, and advanced security features on the ESP32-P4-ETH board.

In terms of software support, the ESP32-P4-ETH can be programmed with the ESP-IDF framework or the Arduino IDE, with support for LVGL and SquareLine Studio for HMI development. Security features like Secure Boot and Flash Encryption are supported natively in ESP-IDF, while AI speech interaction is enabled through connections to cloud-based large model platforms. 

More information can be found in the wiki, which includes a getting started guide, hardware resources such as schematics, pinouts, and dimensions, and software setup instructions for the Arduino IDE and the ESP-IDF framework. It also includes sample demos for I2C, SDMMC, I2S audio, MIPI DSI displays, LVGL HMI, and an ESP-Phone interface.

The ESP32-P4-ETH board is sold on AliExpress for $17.80 and up. The board is sold standalone or in kits: with a PoE module (POE-ETH – $23.99), a camera and a speaker (KIT-A – $33.43), or a full “Kit-B” bundle adding a 10.1-inch LCD for a total of $88.87. You’ll also find these on Amazon and the Waveshare store, where prices are a little lower: $12.99 for the board and $69.99 for the KIT-B bundle.
