Waveshare 32152 Industrial 1-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 5 (LE) dual-mode wireless communication with excellent 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 RTC chip to support scheduled tasks. Equipped with an onboard USB Type-C port for power supply, firmware downloading, and debugging. Includes an onboard terminal block for power input (supports 5V power supply only). Features onboard optocoupler isolation to prevent external high-voltage relay circuits from interfering with the control chip. Includes onboard digital isolation to prevent external signals from interfering with the control chip. Features onboard integrated power isolation to provide stable isolated voltage; no additional power supply is required for the isolated side. Includes onboard RS485 transceiver indicators for easy monitoring of device operating status. Comes with a DIN-rail mountable protective enclosure for convenient installation and enhanced safety
