Waveshare 26756 Industrial 6-Channel ESP32-S3 WiFi Relay Module Supports WiFi / Bluetooth / RS485 control

Based on the ESP32-S3 microcontroller, featuring an Xtensa 32-bit LX7 dual-core processor with a clock speed of up to 240MHz

1. 4GHz Wi-Fi and Bluetooth LE dual-mode wireless communication, offering superior RF performance. Uses a high-quality relay supporting loads up to 10A at 250V AC or 10A at 30V DC. Features an onboard isolated RS485 interface for easy connection to various RS485 Modbus industrial expansion modules or sensors. Includes an onboard Pico-compatible interface, supporting select Raspberry Pi Pico expansion boards to add functions such as RTC, CAN, RS232, LoRa, and sensors. Equipped with an onboard USB Type-C port for power supply and debugging, facilitating development. Features a terminal block power input supporting a wide voltage range (7–36V), suitable for industrial power applications. Incorporates onboard optocoupler isolation to prevent external high-voltage relay circuits from interfering with the control chip. Includes onboard digital isolation to protect the control chip from external signal interference. Features onboard integrated power isolation, providing stable isolated voltage without requiring an external power supply for the isolated side. Includes an onboard buzzer, RGB LED, and status indicators for power and RS485 TX/RX, allowing for easy monitoring of the devices operating status. Housed in a DIN-rail mountable ABS protective case for safe and convenient installation and use
