The manual pin toggle works flawlessly for quick switching, and the 5V logic level is clean enough to drive straight from an Arduino without extra circuitry. I've had it running for a week straight and not a single hiccup.

Setting up the manual digital pin control was a breeze, and the board responded instantly when I toggled it with my Arduino. It’s a solid little 5V module that does exactly what it says, and the screw terminals make wiring up loads secure.

Using the I2C interface to control multiple relays from my Arduino freed up GPIO pins I desperately needed for sensors. It responds instantly to commands
