ESP32-C6-EVB Evaluation Board Schematic
Schematic for the Olimex ESP32-C6-EVB featuring the ESP32-C6-WROOM-1 module, four relays, four optoisolated inputs, and 8-50VDC power input for industrial IoT applications.
Overview
This schematic design document covers the hardware architecture of the Olimex ESP32-C6-EVB evaluation board. Centered on the Espressif Systems ESP32-C6-WROOM-1-N4 module, the board supports Wi-Fi 6, Bluetooth 5, and Matter protocols. Key integrated components include four Rayex RAS-0515 relays for power switching and four Sharp PC817CS optoisolated inputs for signal conditioning. The power management section utilizes a Taisic TX4138 buck converter to support a wide input range of 8-50VDC, alongside a Silergy SY8089AAAC regulator for 3.3V rails. The design includes a USB-C interface for programming/JTAG debugging and Olimex's UEXT connectors for modular expansion.
Use Cases
- Industrial automation and remote monitoring
- IoT device prototyping with Wi-Fi 6 and Matter
- Mains power switching using integrated relays
- Isolated digital signal interfacing
- ESP32-C6 hardware evaluation and firmware development
