Industrial 1-Channel ESP32-S3 Wi-Fi Relay Module, Uses the External Antenna

Powerful dual-core main control, dual-mode wireless communication---Based on ESP32-S3 microcontroller, equipped with Xtensa 32-bit LX7 dual-core processor, clocked at 240MHz
integrated 2.4GH z Wi-Fi and Bluetooth 5 (LE) dual-mode wireless communication, with excellent radio frequency performance.
10A strong load relay, multiple isolation protection---High-quality relays allow access to loads 10A 250V AC or 10A 30V DC
onboard optocoupler isolation, digital isolation, and integrated power isolation prevent external high voltage or external signals from interfering with the control chip, and no additional power supply is required at the isolation end.
Onboard isolated RS485 interface---Supports external expansion access to various RS485 Modbus industrial expansion modules or sensors.
Onboard R T C clock chip---The onboard R T C clock chip supports timing tasks and meets the needs of automated applications such as timing switches and periodic control.
5. Dual power supply interfaces, convenient development and installation---The onboard USB Type-C interface can be used for power supply and download debugging
the onboard terminal block power supply interface (only supports 5V power supply)
the onboard RS485 transceiver indicator light for easy viewing of operating status
the rail-type protective shell for easy installation, and the shell is safer.
