1 channel 5V relay module Board is a compact, single-channel optocoupler-isolated relay shield for controlling one high-voltage or high-current device from a low-voltage Arduino, ESP32, Raspberry Pi, or any 5V microcontroller. Featuring the JQC-3FF-S-Z relay and selectable high/low level triggering, it’s the simplest and most reliable way to add AC or DC switching capability to any microcontroller project.
Typical Applications:
- Home automation and smart switching projects
- Motor, pump, and fan control
- Lighting automation systems
- Industrial automation control
- IoT switching and remote control
- Embedded control projects
- DIY electronics applications
- Arduino relay switching experiments
