ESP32-P4-Module (esp32-p4c5miniboard)
The ESP32-P4-Module is a high-performance, versatile embedded core system module. Its design is centered around the ESP32P4C6/ESP32P4C5 core board.
This module provides an extremely rich set of peripheral interfaces and functional units, including camera (CSI), display (DSI), audio, USB, and various power protection circuits. It is specifically designed for advanced IoT applications requiring complex human-machine interaction, multimedia processing, multi-protocol wireless connectivity, and high-speed data communication.
Features
- High-Performance MCU: Equipped with RISC-V 32-bit dual-core and single-core processors.
- Memory Architecture: 128 KB HP ROM, 16 KB LP ROM, 768 KB HP L2MEM, 32 KB LP SRAM, 8 KB TCM.
- Multimedia Processing: Integrated JPEG codec, Pixel Processing Accelerator (PPA), Image Signal Processor (ISP), and H264 video encoder.
- Integrated Memory: In-package stacked 32 MB PSRAM and external 16 MB Serial Flash.
- Extensive I/O: 2*2*17 pins, leading out 55 programmable GPIOs from ESP32-P4 and 9 GPIOs from ESP32-C6/ESP32-C5.
- Wireless Connectivity: Supports Wi-Fi 6 and Bluetooth 5.0 (LE).
- Security: Secure boot, Flash encryption, hardware cryptographic accelerators (AES, SHA, RSA, ECC, RNG), and hardware access protection (APM).
