S1: It is option switch for channel 1 relay 2. S2: It is option switch for channel 2 relay Package:2 pcs

Review: works good but each channel is separate - need to add a jumper wire if you want to have both channels controlled by 1 input, but they work well and a bargain for the price - terminals are hard if you don't know to place wire to one side as the screw is in the middle.
Review: Perfect for Arduino - I bought this item for my students and they used it in their Arduino circuits. Works very well with no complain at all

### ⭐⭐⭐⭐⭐ works good but each channel is separate
*by A***K on January 21, 2024*

need to add a jumper wire if you want to have both channels controlled by 1 input, but they work well and a bargain for the price - terminals are hard if you don't know to place wire to one side as the screw is in the middle.

### ⭐⭐⭐⭐⭐ Perfect for Arduino
*by F***D on December 3, 2022*

I bought this item for my students and they used it in their Arduino circuits. Works very well with no complain at all

### ⭐⭐⭐⭐ Works with Raspberry Pi
*by A***G on August 21, 2020*

I'm using this with two Raspberry Pi boards (one a 3B+, the other a 2B) connecting both the 5V to power the solenoid board and using the PI 3.3V GPIO to turn on/off. One of the 4 units was defective out of the box but the others are working. For the money, they are a good choice. Note that there is a severe limit on the current available for GPIO switching from the Pi, so the single-channel model would be the only viable choice. I am able to use this to power a 3D printer on/off by switching the AC power using the OctoPrint PSU control add-in, which simply raises a configurable GPIO pin.
