ESP32-EVB Rev K Bill of Materials
Bill of materials for the Olimex ESP32-EVB Rev K evaluation board featuring ESP32-WROOM-32, Ethernet, CAN, relays, and power management components.
Overview
This bill of materials document details the electronic components used in the Olimex ESP32-EVB Rev K evaluation board. The design is centered around the Espressif ESP-WROOM-32 module for Wi-Fi and Bluetooth connectivity, supported by a Microchip LAN8710A Ethernet PHY and a SIT1050T CAN transceiver. Power management is handled by a Silergy SY8089 buck converter and a Shanghai Belling BL4054B battery charger. The board includes two RAS-0515 relays for power switching, an infrared receiver/transmitter pair, a Micro SD slot, and a CH340T USB-to-UART bridge for programming.
Use Cases
- Industrial automation and monitoring
- IoT gateway development with Ethernet and Wi-Fi
- Remote relay control and switching
- CAN bus communication prototyping
- Battery-powered IoT sensor nodes
