ESP32-EVB Rev K2 Bill of Materials
Bill of Materials (BOM) for the ESP32-EVB Rev K2 board, featuring the ESP32-WROOM-32E module, Ethernet, CAN bus, dual relays, and LiPo charging.
Overview
This document provides a comprehensive list of components for the ESP32-EVB Revision K2 evaluation board. The design is centered on the Espressif ESP32-WROOM-32E-N4 module and includes specialized circuitry for industrial and IoT connectivity. Key components include the Microchip LAN8710A-EZC for 10/100 Ethernet, a Silicon Internet of Things SIT1050T CAN transceiver, and dual Sun Hold RAS-0515 relays for power switching. Power management is handled by a Silergy SY8089AAAC buck regulator and a Top Power TP4054 battery charger. The board also features a WCH CH340T USB-to-UART bridge, a microSD card slot, and an infrared interface using a VS1838B receiver and IR333-A LED.
Use Cases
- Industrial IoT (IIoT) gateway development
- Home automation systems requiring relay control
- Remote monitoring with wired Ethernet and CAN connectivity
- Embedded web server implementation
- Battery-powered wireless sensor nodes with charging capabilities
