The Waveshare Industrial ESP32‑S3 Control Board brings robust, industrial-grade control to AIoT applications. Featuring eight optocoupler-isolated digital inputs and outputs (each supporting up to 500 mA sink capacity via Darlington transistors), this board is built around the powerful dual-core ESP32‑S3 processor with Wi‑Fi, Bluetooth LE, RS‑485, CAN, Ethernet (via W5500), and PoE support. Housed in a rail-mount ABS enclosure, it includes USB-C programming, wide 7–36V power input, isolation protections, onboard buzzer, RGB LEDs, RTC, TF card slot, and an antenna connector—making it your go-to solution for safe, reliable industrial control systems. Features: Based on ESP32-S3 microcontroller with Xtensa 32-bit LX7 dual-core processor, capable of running at 240 MHz Integrated 2.4GHz Wi-Fi and Bluetooth LE dual-mode wireless communication, with excellent RF performance The outputs adopt Darlington transistors with optocoupler isolation, delivering higher drive capability with a sink current of up to 500 mA, and feature built-in flyback diode protection Supports passive and active digital input, with bi-directional optocoupler isolation. The digital output supports digital input linkage control Onboard isolated RS485 interface, for connecting to various RS485 Modbus industrial modules or sensors Onboard isolated CAN interface, for connecting to various CAN devices Onboard pin header, allowing access to other devices Onboard USB Type-C port for power supply, firmware downloading and debugging Onboard power supply screw terminal, supports 7~36V wide voltage input, suitable for industrial applications Onboard RTC chip, supports scheduled tasks Onboard W5500 Ethernet chip for extending 10/100Mbps network port through SPI interface Built-in PoE module for PoE capability (compliant with IEEE 802.3af standard) Onboard optocoupler isolation to prevent interference from external circuit Onboard digital isolation to prevent interference from external signal Onboard unibody power supply isolation, providing stable isolated voltage, no extra power supply required for the isolated terminal Onboard TF card slot for external TF card storage of images and files Built-in buzzer, RGB LED, power supply, RS485 and CAN TX/RX indicators for monitoring the operating status of the devices Rail-mounted protective case, easy to install, safe to use Package Includes: 1 x Waveshare Industrial ESP32-S3 Control Board1 x 2.4G 4DB SMA antenna1 x Screw Driver
