ESP32-P4-Pi Board Combines Wi-Fi 6, Ethernet, and Pi Form Factor

VIEWE has introduced the ESP32-P4-Pi-VIEWE, a Raspberry Pi-like development board built around the ESP32-P4 RISC-V processor and featuring an ESP32-C6 for wireless connectivity. Designed for multimedia, HMI, edge AI, and industrial IoT applications, while maintaining compatibility with Raspberry Pi accessories and enclosures with its standard 85 x 56 mm layout and 40-pin GPIO header.

The development board includes various multimedia features such as MIPI-CSI camera input with ISP, MIPI-DSI display output, H.264 encoding, and hardware acceleration (PPA), plus voice capabilities with dual microphones, echo cancellation (ES7210), and audio codec (ES8311). Connectivity options include 100 Mbps Ethernet with optional PoE, USB 2.0 OTG/host, microSD, and a 40-pin GPIO header compatible with Raspberry Pi accessories, exposing interfaces such as UART (RS-485), I2C, SPI, and CAN. Additional features include a 6-axis IMU, camera, and display connectors.

The board appears to target applications such as smart home control panels, industrial automation systems, service robots, multimedia terminals, smart appliances, and edge AI devices. Espressif also positions the ESP32-P4 platform as a lower-power alternative to Linux SBCs for real-time HMI and multimedia workloads.

Previously, we have covered several ESP32-P4-based platforms, including the Waveshare ESP32-P4-WIFI6-POE-ETH development board, the ESP32-P4-WIFI6, and the Waveshare ESP32-P4 board, all of which are designed for multimedia and AI-edge applications and feature similar Wi-Fi 6-enabled architectures

Software support includes ESP-IDF, while support for the Arduino IDE and PlatformIO is currently under development. VIEWE also provides LVGL examples and display libraries for GUI-focused projects. More information can be found on the wiki page and GitHub.

The ESP32-P4-Pi-VIEWE development board is available from the company’s official store for $17.99.
