Waveshare 8-Channel ESP32-S3 WiFi Relay Module with RS485 & PoE Ethernet – Xtensa 32-bit LX7 Dual-Core Processor
Waveshare 8-Channel ESP32-S3 WiFi Relay Module with RS485 & PoE Ethernet – Xtensa 32-bit LX7 Dual-Core Processor
Waveshare 8-Channel ESP32-S3 WiFi Relay Module with RS485 & PoE Ethernet – Xtensa 32-bit LX7 Dual-Core Processor
The Waveshare ESP32-S3-ETH-8DI-8RO is an industrial-grade 8-channel WiFi relay module designed for IoT automation, remote control, and industrial monitoring applications. At its core is an ESP32-S3 microcontroller with a dual-core Xtensa 32-bit LX7 processor running at up to 240 MHz, along with 2.4GHz WiFi and Bluetooth LE for wireless connectivity.
The module combines 8 relay channels, 8 isolated digital inputs, an isolated RS485 interface, and Ethernet connectivity, making it suitable for controlling and monitoring multiple devices from a single controller. The PoE variant additionally supports IEEE 802.3af PoE, allowing network communication and power to be delivered through Ethernet.
With optocoupler isolation, digital signal isolation, power isolation, wide 7–36V input support, USB Type-C connectivity, and a rail-mount ABS enclosure, this ESP32-S3 relay board provides a practical solution for smart factory systems, building automation, industrial IoT, and other connected control applications.
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 for enhanced RF performance.
- High-quality relay with contact rating of ≤10A at 250V AC/30V DC.
- Supports both passive and active digital input, as well as bidirectional optocoupler isolation. The relay enables digital input linkage control.
- Onboard isolated RS485 interface, to connect to numerous RS485 Modbus industrial modules or sensors.
- 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.
- Optional PoE network port version with built-in PoE module for PoE functionality (compatible with IEEE 802.3af standard).
- Onboard optocoupler isolation to avoid interference from an external high-voltage circuit linked to the relay
- 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, and RS485 TX/RX indicators to monitor the devices' functioning state.
- Rail-mounted ABS enclosure is easy to install and safe to use.
