ESP32-P4-Module User Guide

Overview

Introduction

ESP32-P4-Module is a dual-core RISC-V high-performance module based on ESP32-P4 chip designed by Waveshare, using ESP32-C6H8 to expand WIFI6 functionality. It supports a wide range of human-computer interfaces, including MIPI-CSI (Integrated Image Signal Processor, ISP) and MIPI-DSI interfaces, as well as common peripherals such as SPI, I2S, I2C, LED PWM, MCPWM, RMT, ADC, UART, and TWAI™. It also supports USB OTG 2.0 HS, Ethernet, and SDIO Host 3.0 for high-speed connectivity. The chip integrates a digital signature peripheral and a dedicated key management unit to ensure its security. ESP32-P4-Module is specifically designed for high-performance and high-security applications, fully meeting the higher demands of embedded applications for human-machine interface support, edge computing capabilities, and IO connectivity features.
