Waveshare Industrial ESP32 S3 POE ETH Control Board with 8-Channel Digital I/O, Dual-Core LX7 Processor & PoE Ethernet
The Waveshare Industrial ESP32-S3 POE ETH 8DI 8DO Control Board is an industrial-grade ESP32-S3 control solution designed for reliable digital I/O control, automation, and AIoT applications. It is powered by an Xtensa 32-bit LX7 dual-core processor running at up to 240 MHz and provides 8-channel digital input and 8-channel digital output for connecting switches, sensors, actuators, and other industrial equipment.
The board supports 2.4GHz Wi-Fi (802.11 b/g/n), Bluetooth 5 LE, 10/100 Mbps Ethernet, IEEE 802.3af PoE, isolated RS485, and isolated CAN, giving it flexible wired and wireless communication options. Its digital inputs support 5–36V passive or active NPN/PNP signals, while the digital outputs support 5–40V open-drain operation with up to 500mA load current per channel and optocoupler isolation.
For industrial power requirements, it accepts 7–36V DC through the screw terminal or 5V/1A through USB Type-C. Built-in power isolation, digital isolation, optocoupler protection, TVS protection, surge protection, and ESD protection help provide stable operation in demanding environments.
The board also includes a W5500 Ethernet controller, RTC, TF card slot, buzzer, programmable RGB LED, USB Type-C interface, and 35mm rail-mount protective enclosure, making it suitable for industrial automation, remote I/O control, IoT gateways, smart factory systems, and embedded control projects.
Features:
• Based on the ESP32-S3 microcontroller with Xtensa 32-bit LX7 dual-core CPU capable of running at 240 MHz.
• Integrated 2.4GHz Wi-Fi and Bluetooth LE dual-mode wireless connection, with outstanding RF performance.
• The outputs use Darlington transistors with optocoupler isolation, providing increased drive capacity with a sink current of up to 500 mA, and include built-in flyback diode protection.
• Supports both passive and active digital input, as well as bidirectional optocoupler isolation. The digital output enables digital input linkage control.
• Onboard isolated RS485 interface, to connect to numerous RS485 Modbus industrial modules or sensors.
• Onboard isolated CAN interface to connect to numerous CAN devices.
• Onboard pin header provides access to other devices.
• Onboard USB Type-C port for power supply, firmware download, and debugging.
• The onboard power supply screw connector offers a wide voltage input range of 7-36V, making it suited for industrial applications.
• The onboard RTC chip facilitates scheduled tasks.
• Onboard W5500 Ethernet chip extends 10/100Mbps network port via SPI interface.
• Built-in PoE module with PoE functionality (compatible with IEEE 802.3af standard)
• Onboard optocoupler isolation to prevent interference from the external circuit.
• Onboard digital isolation prevents interference from external signals.
• Onboard unibody power supply separation provides stable isolated voltage; no additional power supply is required for the isolated terminal.
• Onboard TF card slot for external image and file storage.
• Built-in buzzer, RGB LED, power supply, RS485 and CAN TX/RX indicators to monitor the devices' functioning state.
• Rail-mounted protective case is easy to install and safe to use.
