Waveshare ESP32-P4-ETH
The Waveshare ESP32-P4-ETH is a Pico-form-factor development board built around the ESP32-P4 RISC-V dual-core processor with an onboard 100Mbps Ethernet port via the IP101GRI PHY. It provides reliable wired networking for industrial and IoT applications where WiFi is not suitable, with a PoE module header for power-over-Ethernet deployments.
Key Highlights
- High Performance: ESP32-P4 dual-core RISC-V at 400MHz with AI extensions and FPU
- Wired Ethernet: 100Mbps RJ45 port via IP101GRI PHY with auto-negotiation
- PoE Ready: Onboard PoE module header for IEEE 802.3af/at power delivery
- Rich Memory: 32MB PSRAM (OPI) + 32MB NOR flash + 768KB on-chip SRAM
- Display and Camera: 2-lane MIPI-DSI (5/7/8/10.1-inch screens) and 2-lane MIPI-CSI with integrated ISP
- Video Processing: Hardware H.264 encoder (1080p at 30fps), JPEG codec, PPA 2D graphics accelerator
- Audio System: ES8311 codec + NS4150B amplifier + MEMS microphone + speaker connector (8 ohm 2W)
- Storage: SDIO 3.0 microSD slot (up to 40MHz high-speed)
- USB: Type-C for power/UART + USB 2.0 OTG HS port
- Expansion: 2x20 pin header with 27 programmable GPIOs, Pico HAT compatible
- ESPHome Support: Compatible with ESPHome for Home Assistant integration
No Wireless
Like the base ESP32-P4-Pico, this board has no WiFi or Bluetooth. It relies on wired Ethernet for network connectivity, making it ideal for fixed installations requiring stable connections.
