Overview

Detailed design document for the Olimex ESP32-P4-DevKit (Revision B), centered on the Espressif Systems ESP32-P4NRWxx SoC. The circuit integrates 16MB of Winbond W25Q128JVSIQ flash memory and an IC Plus Corp IP101GRR PHY for 10/100 Ethernet via a LINK-PP RJ45 connector. Power management is handled by Texas Instruments TPS62A02ADRLR DCDC converters. The board includes dedicated MIPI CSI and DSI connectors for camera and display peripherals, a MicroSD card slot, and a USB-C interface for debugging and power. It also features standard expansion headers and Olimex's proprietary pUEXT connector.

Use Cases

  • High-performance IoT gateway development
  • Human-Machine Interface (HMI) with MIPI display
  • Embedded vision systems using MIPI CSI camera
  • Industrial networking and automation
  • Prototyping RISC-V based multimedia applications
