It combines 8 relay outputs, 8 digital inputs, isolated CAN, Ethernet, Wi-Fi and Bluetooth for control panels, robotics, smart factories and advanced home automation systems.The module is designed to reduce the extra wiring and interface boards often needed between IoT controllers and industrial equipment. Optocoupler isolation, digital isolation, TVS diodes and a wide-voltage power supply help protect the logic side when switching higher-voltage or noisy loads.It comes housed in an industrial-grade ABS enclosure for rail mounting, with screw terminals for field wiring. Onboard peripherals include RTC, TF/MicroSD storage, a programmable RGB LED and buzzer for status indication and local feedback.Features:Relay control: Control heavy inductive and resistive loads securely with 8 mechanical relays.Relay rating: Relays are capable of switching up to 10A at 250V AC or 30V DC.Relay isolation: Optocoupler isolation helps protect digital logic from high-voltage feedback.Local processing: Process complex automated routines locally using the ESP32-S3 dual-core microcontroller.Memory: Equipped with 16MB of Flash and 8MB of PSRAM.Software support: Suitable for demanding MicroPython, C++, or Arduino scripts.CAN interface: Onboard isolated CAN interface for automotive or industrial sensor networks.Noisy environments: CAN interface supports reliable data transmission in electrically noisy environments.Ethernet: Built-in W5500 Ethernet port for stable, low-latency wired networking.Wi-Fi: Native 2.4GHz Wi-Fi for wireless networking.Bluetooth: Native Bluetooth 5 (BLE) capability.Digital inputs: Read sensor states or physical switches safely via 8 flexible digital inputs.Input modes: Supports both active and passive switching mechanisms.Input tolerance: Digital inputs support input tolerance up to 36V.Panel mounting: Industrial ABS rail-mount enclosure for existing electrical panels.Power input: Wide 7V to 36V DC input range.Status LED: Onboard programmable RGB LED for custom visual feedback.Status indication: RGB LED can show at-a-glance status updates such as network connection or fault states.OEM part: Genuine Waveshare OEM part.Support: Backed by extensive documentation and long-term support.Specifications:Microcontroller: ESP32-S3-WROOM-1U-N16R8 (Xtensa 32-bit LX7, up to 240MHz)Memory: 16MB Flash, 8MB PSRAMRelays (Outputs): 8 Channels (1NO 1NC), Rated ≤10A 250V AC / 30V DCDigital Inputs: 8 Channels, 5V to 36V DC (Passive/Active - NPN or PNP)Wired Connectivity: Isolated CAN bus, Ethernet (10/100Mbps via W5500), USB Type-CWireless Connectivity: 2.4GHz Wi-Fi (802.11 b/g/n), Bluetooth 5 / BLEPower Supply: 7V to 36V DC via screw terminal, or 5V via USB-CIsolation Protections: Optocoupler isolation (relays/inputs), unibody power supply isolation, digital signal isolation, TVS diodesOnboard Peripherals: RTC (Real Time Clock), TF / MicroSD card slot, Programmable RGB LED, BuzzerEnclosure: Industrial-grade DIN-rail mount ABS plasticA strong fit for industrial automation, remote I/O, equipment control and connected relay applications where ESP32-S3 processing, isolated field inputs and multiple network interfaces are needed in one enclosure. **Product Type:** Industrial Relay Module ## Images - [Image 1](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDgDUDSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--3a23b85a71a278f6c89c927cee6aa5e9e15b161e/esp32-s3-eth-8di-8ro-c-1.jpg) - [Image 2](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDgTUDSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--fc14cece54662fd469dd6c630b35bc806f1c6d5e/esp32-s3-eth-8di-8ro-c-2.jpg) - [Image 3](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDgjUDSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--dba590e02a12ce0881ffae24d061cfdbd8536bd8/esp32-s3-eth-8di-8ro-c-3.jpg) - [Image 4](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDgzUDSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--ff94bca9238ab36900c4d9d3203b72e7bbf851a9/esp32-s3-eth-8di-8ro-c-4.jpg) - [Image 5](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDhDUDSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--a6d3ac728b40c46de7bbf962b541faf410b6ebcf/esp32-s3-eth-8di-8ro-c-5.jpg) --- ## Finding & Searching Products If a part listed here isn't quite what you need, you can search Little Bird Electronics' full catalogue: - **Search by keyword:** `GET https://littlebirdelectronics.com.au/products.md?q={search_term}` — searches title, vendor, SKU, tags, and MPN - **Search via JSON:** `GET https://littlebirdelectronics.com.au/products.json?q={search_term}` — structured JSON results - **Browse by collection:** `GET https://littlebirdelectronics.com.au/collections/{handle}.json` — products in a specific collection - **Filter in-stock only:** `GET https://littlebirdelectronics.com.au/products.md?q={term}&in_stock=1` - **Individual product detail:** `GET https://littlebirdelectronics.com.au/products/{handle}.md` — full specs, pricing, stock levels, variants Search supports multi-word queries (AND logic).
