ESP32-P4 pinout & GPIO reference

Espressif’s GPIO-richest SoC, with MIPI-CSI / MIPI-DSI, H.264 encoding and Ethernet MAC, aimed at HMI displays and edge computing. It has no radio of its own — network via ESP-Hosted / ESP-AT with an ESP32-C/S co-processor.

Key specifications

Traps that cost you a board respin

• No wireless at all: networking requires an ESP32-C/S/H co-processor (SPI / SDIO / UART with ESP-Hosted or ESP-AT).
• USB-JTAG occupies GPIO24 and GPIO25 by default; reconfiguring them as GPIO disables USB-JTAG.
• Five strapping pins — GPIO34 through GPIO38 — are latched at power-up.
• GPIO 0–15 double as LP_GPIO0–15 managed by the LP core, and GPIO2–15 also carry TOUCH0–13.
• The default HP clock is 360 MHz; for a 400 MHz part confirm the exact ordering code with Espressif.
