ESP32-PoE-ISO Rev L Bill of Materials (ESP32-WROOM-32E)
Bill of materials for the ESP32-PoE-ISO Rev L IoT board, featuring the ESP32-WROOM-32E module, Ethernet with PoE isolation, and integrated battery charging.
Overview
This document provides the complete Bill of Materials (BOM) for the Olimex ESP32-PoE-ISO revision L development board. The design is centered on the Espressif ESP32-WROOM-32E module and a Microchip LAN8710A Ethernet PHY. It specifies components for 3000V galvanic isolation, including a Texas Instruments TPS2376D PoE controller, a Terax TX4138, and a Mornsun F0505S-2WR2 DC-DC converter. Additional integrated circuits listed include the WCH CH340T USB-UART bridge, Silergy SY8089 buck regulator, and Belling BL4054B battery charger. The BOM details all necessary passive components, protection diodes, and connectors such as the Link-PP LPJ4112CNL RJ45 jack and a Micro SD slot.
Use Cases
- Industrial IoT sensor nodes requiring PoE isolation
- Building automation systems with wired Ethernet connectivity
- Developing battery-powered IoT devices with PoE charging capabilities
- Procurement and assembly for the ESP32-PoE-ISO hardware revision L
