Your cart is empty. Description:
1. Driving Port Signal Voltage:3.3-24V
2. Output voltage range: 3.6-30V(The output current depends on the specific situation but not over 10MA. When the total power is fixed, the voltage and current are inversely proportional)
NOTE:
The input port is shared with GND;
The output ports are independent of each other;
It is optocoupler output.V and G will be connected after input valid signa in input port;
Package Included:
6 x PC817 2 Channel Optocoupler Isolation Board

I used these for an open auto pro setup to interface between the accessory, illumination, and reverse wires from the car's harness and GPIo on the Raspberry Pi. I'd originally designed around a four-channel relay PCB which worked fine, but as this board makes no clicking sound like mechanical relays and doesn't require much current from the signals to the optocouplers (see the item description). The low current draw from GPIo pins (I added resistors to the circuit as well) makes this a perfect, quiet solution!

I used this to control a 3.3v remote selfie photo circuit using 5v arduino. It works great! 2 channels per board is one more than I need, but its nice knowing I have options.
