Compatibility & Notes
This relay module operates at 5V logic level and is compatible with most Arduino boards. For 3.3V systems like ESP32 or Raspberry Pi Pico, you may need a relay that supports 3.3V triggering or use a level shifter.
If you need PWM-based control such as adjusting brightness or fan speed, consider using the Gravity: MOSFET Power Controller, which is designed for smooth analog power control.
