Then I reckon that would be a significant upgrade compared to my initial question because I will be able to send each camera device a different command or I'll be able to send each device the same command depending on what I want to do with the camera devices. | |

| Dec 7, 2016 at 14:11 | comment | added | jose can u c | If your Vcc is not an LED driver (constant-current source), you will likely want a current-limiting resistor of at least 200Ω. The datasheet you linked to shows a voltage drop of about 1.2V and a current draw of nominal 20mA V/A=R => (5V - 1.2V) / 0.020mA =>190Ω | |
