Waveshare Industrial ESP32-S3 Control Board w/ 8-Channel I/O, RS485, CAN, ETH, PoE
This Waveshare Industrial ESP32-S3 Control Board is a robust, rail-mount IoT gateway built around the dual-core ESP32-S3 with Wi-Fi & BLE, featuring eight opto-isolated digital I/Os, RS-485, CAN, Ethernet, and PoE support for industrial automation and telemetry applications.
Features
- Dual-core ESP32-S3 processor with integrated 2.4GHz Wi-Fi and Bluetooth LE for wireless connectivity and local control.
- Eight optocoupler-isolated digital I/O channels, each capable of sinking up to 500mA via Darlington transistors for direct relay or load control.
- Integrated industrial interfaces: isolated RS-485 and CAN buses, plus a W5500-based 10/100Mbps Ethernet port with IEEE 802.3af PoE support.
- Wide 7–36V DC input range via screw terminal, making it suitable for 12V/24V industrial power rails and harsh electrical environments.
- Rail-mount ABS enclosure with comprehensive onboard peripherals: USB-C, TF card slot, RTC, buzzer, RGB LEDs, and a 4dBi SMA antenna.

The Waveshare Industrial ESP32-S3 Control Board is engineered for demanding industrial IoT and automation scenarios. Its foundation is the Espressif ESP32-S3 microcontroller, featuring a dual-core Xtensa LX7 processor running at 240 MHz, 16 MB of flash, and 8 MB of PSRAM. This provides ample compute for running complex control logic, network stacks like Modbus TCP, MQTT brokers, or lightweight web servers directly on the edge device.
Communication robustness is ensured through multiple isolated interfaces. The board includes a fully isolated RS-485 transceiver for connecting to Modbus RTU sensors and actuators, an isolated CAN controller for automotive or industrial bus networks, and a W5500 hardwired TCP/IP chip delivering a stable 10/100Mbps Ethernet connection. An integrated PoE module compliant with IEEE 802.3af allows for both data and power delivery over a single Ethernet cable, simplifying installation. The eight digital I/O channels are a standout feature, each protected by optocouplers and driven by Darlington transistors capable of sinking 500mA, enabling direct interface with industrial solenoids, relays, or indicator lamps without external drivers.
Built for reliability, the board incorporates multi-domain isolation: optocoupler isolation for digital I/O and serial buses, digital signal isolation, and a unibody isolated DC-DC converter that provides clean power to the isolated side without needing an external supply. Housed in a DIN-rail mountable ABS case, it includes practical features like a USB-C port for programming and debugging, a microSD (TF) card slot for data logging or firmware updates, a real-time clock (RTC) for time-based scheduling, and status indicators for power, network activity, and I/O states. The wide 7–36V input range ensures compatibility with standard 12V and 24V DC systems common in factories, warehouses, and infrastructure projects.
