ESP32-P4-DevKit Rev.B Electronics Design Document
Hardware schematic for the Olimex ESP32-P4-DevKit featuring the ESP32-P4 SoC, 10/100 Ethernet, MIPI CSI/DSI interfaces, 16MB flash, and USB-C JTAG/Serial connectivity.
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
