Olimex ESP32-PoE-ISO Rev J Bill of Materials (WROOM)
Bill of materials for the ESP32-PoE-ISO Rev J IoT board, featuring isolated PoE, ESP32-WROOM-32E module, LAN8710A Ethernet PHY, and Li-Po battery charging circuitry.
Overview
This document is a comprehensive bill of materials (BOM) for the Revision J hardware design of the Olimex ESP32-PoE-ISO development board. The design is centered on the Espressif ESP32-WROOM-32E module and incorporates isolated Power over Ethernet (PoE) using a Texas Instruments TPS2375 controller and a Mornsun F0505S-2WR2 isolated DC-DC converter. Essential components listed include the Microchip LAN8710A Ethernet PHY, WCH CH340T USB-UART bridge, and power management ICs like the Silergy SY8089AAAC and Beling BL4054B battery charger. The document details all passive components, protection diodes such as the ESDS314 and SMAJ58A, and mechanical parts required for the board's Ethernet, USB, and microSD interfaces.
Use Cases
- Industrial IoT gateways requiring galvanic isolation
- Building automation and control systems using wired Ethernet
- PoE-powered remote sensor nodes with battery backup
- Wired ESP32 development and prototyping
