ESP32-P4-M3 module — dual-core RISC-V, 32MB Flash, 16MB PSRAM, ISP, H.264

The ESP32-P4-M3 is a high-performance system-in-package (SiP) module from Espressif Systems, built around the ESP32-P4 SoC — a powerful dual-core RISC-V processor designed for demanding HMI, machine vision, and edge AI applications. Unlike previous ESP32 variants, the ESP32-P4 does not include built-in Wi-Fi or Bluetooth; wireless connectivity is achieved via a companion chip (e.g. ESP32-C6 or ESP32-H2) connected over SPI/SDIO.Key Specifications: SoC: Espressif ESP32-P4 CPU: Dual-core RISC-V (HP core @ up to 400 MHz, LP core @ 40 MHz) Flash: 32MB (octal SPI) PSRAM: 16MB (octal SPI) Image Signal Processor (ISP): built-in hardware ISP pipeline Video encoder: H.264 hardware encoder Display interface: MIPI-DSI (up to 1080p) Camera interface: MIPI-CSI (up to 4-lane) USB: USB 2.0 OTG (High Speed) Peripherals: SPI, I2C, I2S, UART, SDIO, TWAI (CAN), MCPWM, ADC, DAC Security: RSA-3072, AES-128/256, SHA, HMAC, digital signature Operating voltage: 3.3V Operating temperature: −40°C to +85°C Wireless: None on-chip (requires companion module) Memory: On-chip SRAM: 768KB HP SRAM + 32KB LP SRAM External Flash: 32MB (on module) External PSRAM: 16MB (on module) Key Interfaces: MIPI-DSI: up to 2-lane, for high-resolution display output MIPI-CSI: up to 4-lane, for camera input USB 2.0 OTG HS: 480 Mbps SDIO: for SD card or Wi-Fi companion chip 2× SPI, 3× UART, 2× I2C, 3× I2S Applications: High-resolution HMI panels and smart displays Machine vision and edge AI inference IP cameras and video streaming devices Industrial control panels Smart home hubs with display Medical imaging devices Note: The ESP32-P4 does not include Wi-Fi or Bluetooth. For wireless connectivity, pair with an ESP32-C6 (Wi-Fi 6 + BT 5) or ESP32-H2 (Thread/Zigbee) module via SDIO/SPI. Espressif IDF v5.3+ is required for ESP32-P4 support.
